With only 374 votes among the thousands (millions?) of Illustrator users throughout the world, this is obviously only affecting certain people. The question begged is "what is the cause?" I beta test a web-based software platform and recently some of our team caught a certain defect, but our development team couldn't reproduce it (hence why it wasn't caught before releasing to testers). It wasn't until someone was in a video chat with the dev team that one of the developers saw the Grammarly icon in the text box and asked what it was. After further review, it turned out that Chrome extensions were affecting the way the software was saving/displaying text in a certain location. Something like that is likely also true here. Since none of Adobe's testers caught the bug before release and only certain users are responding with it, it's likely that there is a problem with Illustrator interacting with something else that only certain users are using (and it just so happens that none of Adobe's testers had that combination--hence why the defect made it into the release). Short of asking everyone on this thread every other app/extension/etc. that is running on their computers while they use Illustrator, their dev team probably has to frantically check all kinds of combinations that might be causing this issue. Hopefully, they'll figure it out soon. In the meantime, they've given us two viable workarounds: roll back to 22 or try 23.01 beta. None of us should be "losing money"--we have fixes available. The only reason you should still have the issue is if you haven't done the fix--that's on you, not them. None of us should be expecting "reimbursement." I understand that you're angry, but let's try to think about it from their perspective instead of just dumping hate onto this feed. It isn't helping anyone.

Ashutosh,
Installed yesterday and it has worked great with the preview issue. So far no errors or crashing. Thanks so much again!

I was also using the beta version without this issue and on the release build still don't get this issue. We only have 1 Mac in the studio that we get this error on which is exactly the same spec as mine.

I installed the version released this morning and for now it seems to work much better. The software did not give black and white and preview problems.

Simon Bowland: even though I can agree on your note that blaming Adobe with harsh words is counterproductive, you can´t dismiss the fact that as of now, this issue has 374 votes and a large number of comments from people around the world having Exactly the same issue. From Mac users and Windows users, with completely different hardware. So even though you have tested it, it still doesn´t explain why people having problems. Your comments, does not help either.

"How did your "multiple beta testers" miss such a widely-reported bug is beyond me."

To be fair to Adobe: I was beta-testing 23.0 for more than a month, in various different stages of development, and I never saw this memory/preview problem once. I still haven't seen it with the final release version of 23.0, so it's clearly only affecting certain users and not others.

"Please accept my sincere apology for the inconvenience and disappointment the issue has caused. We do test our products thoroughly including running it through multiple beta testers and we really regret that this issue slipped past our quality checks."

How did your "multiple beta testers" miss such a widely-reported bug is beyond me.

Ho installato il nuovo aggiornamento, vedremo se sono stati corretti tutti i bug.

@Ashutosh: I have upgraded to 23.0.1 following your suggestion and the proccess has been extremely well. And I have been playing around 30 minutes with the app without problems.

I need to leave it (no really need Illustrator today for my tasks) but it would be fantastic if some other heavy user could made more extensive tests.

This is affecting me as well. Crashing constantly since I installed V23.0.

@Dan
I am sorry to hear that. May be you can convince your IT administrators to unblock adobeprerelease site it is a secure site managed by Adobe and has all the security measures that you find on all other Adobe servers.
Another way could be you download it outside your firewall like from home and then take it on an external drive.

Ashutosh,

I am behind a secure system that is having trouble reaching the link you sent. Wondering if there is another way to get it.

@Cristobal: Since the build I posted is a hot fix you do not have to uninstall or trash preferences. The build shall replace the existing install of 23.0.
Please let us know if the fix holds for you.

Thanks for your fix, Ashutosh! :-)

Reading the notes on you link, I suppose that the secure path is:

— Uninstall failed Ai 23.0
— Remove Ai Prefs, just in case…
— Install this new Hotfix 23.0.1 Build 1

Is this right?
THANKS!

I have same issure, it's pretty annoying .... Illustrator keeps crashing for no reason showing up this same message "Cannot finish previewing"

Upgraded to CS 2019 - clean install on new iMac with latest system. Illustrator CC 2019 crashes constantly, mostly when editing paths - says can't preview then changes to wireframe view then moments later crashes. Adobe have looked into it and have been able to replicate the problem - I presume it is being repaired. Surprised this issue is not being reported more! Program is currently unusable.

Reverting back to 2018(v22) is not an option for me since everyone in my work space uses the newer version. If I use 2018(v22) and open a file made in 2019(v23) it will consolidate everything into one layer. I cannot work like that. Found this and it has helped with some of the crashing. Was crashing every other file... now it's about every so many minutes. Still get the RAM issue though... C'est la vie.

Closed Illustrator 2019. Went to Finder, User Library, Caches and delete the com.adobe.illustrator folder
Reopened Illustrator 2019 and went into my preferences, and in Plug-ins & Scratch Disks I changed my Secondary option from none to Macintosh HD. Then closed and reopened Illustrator.

Mac Pro-Late 2013, 2.7 GHz 12-Core Intel Xeon E5, Memory- 64 GB 1866 MGz DDR3, Graphics- AMD FirePro D700 6144 MB

i am getting them left and right. seven times in a row now. i'm not sure but i wonder if it's related to the properties panel constantly changing every time you click on a new object and then "tour" and new feature pop-ups that keep coming up. it seems like all of that is a pretty big drag on resources. but i've got 16gb of ram, so i know that's not the issue.

Had same issue have 16 G of Ram, but only using 35% still getting crashes do to not enough ram.

Mine also doing this, Illustrator 2019 (v23) is unusuable.
Reverted to previous version and the files I saved in the new version won't open in the old version, what is up with that.
