I am pretty sure there is a major memory leak in the last update because Illustrator runs out of "memory" and i can't open any file. 16GB of RAM on a month old iMac is not really the problem because before the update the software worked quite fine. It is really discouraging to use a software that is not cheap and does not work properly after an update. It's not easy build such a complex tool, but pre-release QC should be a norm for a tech giant like Adobe...

Same. I'm still using the roll back of 2018, but since uninstalling and re-installing AI is not showing for system apps. Can't open svg and eps. There's no option in my system to choose Ai as the app.

I have the same issue as Cristobal, my cc apps is showing an illustrator update available but that update is the 23.0.0 version and not the beta 23.0.1 I'm currently using.

Any feedback is appreciated.

@Ashutosh: I have a question/doubt about the Adobe CC automatic updater. Once I applied the 23.0.1 hotfix, now Illustrator goes fine.

But I see that my CC app is NOT detecting Illustrator as an app installed on my machine: it indicates that *I can install Illustrator*, as if it was not really installed!

Is this normal?

I want to believe that once Adobe launch a regular update, then this will change, reflexing that Illustrator (23.0.1) is already installed on my machine? Is that right?

Or what?

Thanks for your feedback! :-)

Applied patch today, can't preview error is fixed, but it will automatically end the program without any warning, and my work will be completely gone....

Applied patch today. Worked several hours in illustrator with zero issues. Thank you!

Applied patch, program seems much more stable. Still have 1 issue that is vexing,
working with live type the program is very slow to respond to highlighting text.
Sometimes the letter/word I want misses and ends up on a different word/letter
because the program is slow to respond. I would ask Adobe to look into how fonts
are handled in the latest update.

OS: Mohave
Font Program: Font Agent latest build.

Otherwise much easier to work with.

ok, when try and turn of the new preference, illustrator crashes. applied the patch with no issue, other than that.

The update seems to have worked, 2 days of constant Illustrator usage and no error messages to report. Is there going to be an official download of this beta version made available?

Ran the update, Illustrator now works just fine. OSX 10.13.6, Chrome, Indesign, Photoshop, MS Word, FontExplorer X Pro.

Along with other issues with the Illustrator 23.0 , I think this one is the most annoying. Im installing older version. I hope it get fixed soon

Also here with this problem since the update. Even fairly simple files are jumping to outline mode or not opening, whereas in the past this was something that only happened if working on a ridiculously complicated file.

I'm running an iMac (Retina 5K, 27-inch, Late 2015)
Processor 3.3 GHz Intel Core i5
Memory: 32 GB 1867 Mhz DDR3
Graphics: AMD Radeon R9 M395X 4096 MB

I usually have a number of apps running concurrently with AI: Chrome (with the following extensions: AdBlock, Amazon Assistant, Application Launcher, Boomerang, Calendly, Cisco Webex, Dropbox, Ebates, Google Docs Offline, Google Keep, GoToMeeting, GoToMeeting Pro Screensharing, Grammarly, Honey, Pinterest, Reader View, Save to Facebook, Search by Image, Soapbox, Fireshot, Wikibuy, Zoom Scheduler), Snagit, Harvest, Republic Anywhere, and occasionally Camtasia, Word, Excel, Powerpoint, Pages, Numbers, Keynote, Firefox, and/or Safari.

I also have 2 peripheral monitors. (Incidentally, I've noticed that when I start AI, the startup screen loads on a side monitor while the rest of the app loads on my main screen--I don't know if there could be anything with AI trying to handle multiple screens.)

When I used 23.0, I would get the "Cannot finish previewing" error about every hour while working in AI. If I didn't quit soon thereafter, AI would crash. Thankfully, the auto-save worked the few times when I didn't save in time. It seemed that if I consistently saved the document, it would take longer between preview errors, but I couldn't say for sure.

23.0.1 seems to be working fine, but I haven't really had a need to push it much yet.

Following up on Casey's comment about possible conflicts between open Apps while using Illustrator v23.0. I thought I would provide my information if it is helpful in trying to debug the issue.

While I have Illustrator open, I also have: Bridge, Photoshop (both 2019), iTunes, MacMail. Occasionally, I have Safari open or Transmit when I am uploading to an ftp, and Acrobat. These last three old remain open if I have to use them in the moment. I am on a iMac running 10.13.6

In the meanwhile I am using v22 with no issues. I may possibly try the fix. Hope this is helpful.

So far so good. Works a treat. Thanks

You misread me. I didn't state that the bug was our fault. My point was that anyone who CONTINUES to be hampered by the bug is at fault for not taking advantage of the available fixes.

If I owned a store and the power went out, so I started losing customers, and I called the electric company and they told me that the electricity was still getting to my building fine and that I should go and check my breakers, but instead of going and flipping the breakers, I instead took the time to write seething comments about the electric company on their website (using my phone because I don't have electricity), I would be a fool.

I also never said that 374 was the total number of users experiencing this issue. I chose my words carefully, mentioning that there were "only 374 votes" among the many Illustrator users. My point was that If this issue was universal, there would be many more votes. Clearly, as you admitted, it is only a segment of the users who are experiencing the issue. And my overall point was that it just so happens that none of Adobe's testers has the same configurations needed to trigger the defect. This kind of thing happens in every workplace--unforeseen complications arise--and no one is benefitted by hateful comments about it. Let's stick to CONSTRUCTIVE criticism and adding information that will actually help Adobe fix this problem.

As for me, so far 23.01 is working fine on my Mac--but I haven't had the need to really push it yet. I was having the Preview issue every hour or so, but I could get by simply by saving often and restarting Illustrator whenever the Preview error came up. I understand that others have had it much worse.

I'm using the version (fix) 23.0.1 from about 1 day and now everything seems to work fine.
no crashes or bugs i can point out.

I do not deny that the problems with the officially released version got me a little disappointed as it came out concurrently with the annual conference.
But after founded the issue with a reinstallation of the previous version I did not waste a lot of time.

376 users do not represent a significant number compared to millions (?) but we must also consider that maybe not all have already installed the new version and not all have written in this forum.

I hope that soon the beta version (23.0.1) became an official (stable) release.

I do not expect refund but, as a subscriber and NOT betatester, Adobe should think to some "benefits" or symbolic discount on the next annual renewal.

The hotfix helped a lot.
The only thing i noticed for today was once a sudden appearing of a serious lag and seconds of freezing, similar to the behaviour right before the crashes happened before. But id did not lead to a crash!
I had to restart the program then and everything was fine again.
Unfortunately I am not shure if this has anything to do with this issue.

@Casey Truelove
If I noticed well,,,most of us who are having problems with Illustrator are using Mac. Why do you think that all of those millions of users out there are also using Mac? Maybe Win guys don't have that issue. Also...why do you think that all who have problems will report that and write here?
When you say ONLY 374...it doesn't mean that no body else have that issue.
I rolled back to previous version of Illustrator few days ago...All is good. I think I will not update it for a while. Blaming this bug on us and our configurations is not professional. This is a company's computer, and beside adobe, I don't use any other software that I didn't use for the past years. If Illustrator worked great in past, and now it doesn't...then I didn't create this issue and bug, but you guys missed something.

I, also, rolled back to 2018 early in the week after reading some of the initial posts. I had lost hours of work.

When opened (2018 version) it's working great. No problems at all within my work space.
However, ALL of my Windows system preferences have been lost. Windows is asking me for all of my default programs, again. Thought I clicked to save preferences.
I can no longer open eps or svg files, at all. They appear as black docs in all of my folder. AI is not even showing in my system programs to choose as a default app? It's obviously on my computer, I'm using it.
Files I'm currently saving, completely disappear. No where to be found.
Clearly I've done something wrong. I admit, but I'm not brave enough to start playing around with Windows system folders.
I guess I assumed the Adobe install and uninstall would take care of these things.
Debating if I should completely uninstall Creative Cloud and all related apps and just start over.
Happy I can at least get work done, now, but really frustrated about all the lost files that equate to hours of work.
