Having exactly the same issues. Need this bug sorted and quickly, come one Adobe, not good enough. Sorry!!!

is there a projected fix date for this bug? please advise the community...

I'm also facing the similar problem "not enough memory" then the preview turns into outline mode. However, I'm able to save the open files. Have to restart the Illustrator to continue my work. Specs of my machine: 13" MacBook Pro Early 2013 + 16GB Ram.

same here on 5 years old windows machine 16GB, no problems before.

reinstalled 2018.

I guess I'm just like many here, I updated in the middle of a client project. Now I apparently don't have enough ram to open my files, which is so not true. Please fix this ASAP, my job is on the line and I don't have time for this.

Having used Illustrator since 1987, I have seen some earlier versions that would occasionally behave this way, but never as a chronic problem. I'd been using v23 for a week or two but did not experience this problem intil today. Also, the files that had been affected disappeared from my directory, but I restored from Time Machine drive and got back to work with v22.
Now I just need toget the time to figure out why my 7-month old iMac has slowed to a crawl--RAM seems intact. Disk 1st Aid says no problems. Any suggestions for a good reliable diagnostic & repair app?
Thanks

Gary, in the excitement of having a shiny new version of Illustrator, I did the very same thing mid-project. You think I would know better by now. Anyways, I reinstalled v22.1 via the Creative Cloud app (Manage -> Other Versions) and I'm back to being operational once again. I was even able to open and edit the files I created with v23. Hope that helps.

This is a nightmare. Now enough memory message then menu at top is greyed out. Even the simplest files freeze. I have enough memory and ram on my mac. Of cause this is in the middle of a project for one of our clients. Any solutions so I can get my work done?

Thank you,
Gary

same thing happening here.

MacOS 10.12.6
iMac Retina 5K 27in Late 2015
4GHz Core i7
32GB RAM
CadTools 11.2 plug-in installed

I'm in the same boat here. after updating to AI 2019. I uninstalled/reinstalled and still suffering the effects of this bug. I've been issuing crash reports as the incidents arise. Please help.

Yes, this just happened to me.

this is ridiculous How do I install the previous version?

This problem has happened at least four times in the past 24 hours since downloading AI 2019 for me. I'm surprised and really disappointed Adobe would release a version with such a huge bug.

Same Problem, multiple crashes with very simple files. Windows 10, 96 GB of RAM. This machine is a graphics workstation, so it has firepower to spare... This memory trap, or whatever it is... well its making me angry...
V 23.

I just updated to the 2019 Illustrator and while I'm in the middle of a project I get a "can't finish preview" dialogue box that pops up and I can't continue my work. I have to shut down and open it all over again to get it to work.

Congrats for the new update!

Here the bugs I've found:

- Sample text (that now shows your actual text, which is a great feature), but it just don't works every time, sometimes it gets slow to show your actual text other it appears the classic "sample"... This feature is quite useful, please check this!

- From time to time (like 2-4 times a day) illustrator crashes and make a force quit.

- Sometimes it says "not enough memory" and crashes (I have a 3.500€ iMac)

- New gradient tool is awesome, but when you pick the color on the point you just created, that point blinks... Is not big deal, just to let you know.

- I had one problem with the first window (where you search vastest project and paper sizes). It just went crazy a couple of times (super zoom so you couldn't do anything, very very very small window on left top corner so impossible to do something, etc)

I used to leave open Photoshop, Safari, Slack, Upwork Chat, and Spotify.

My iMac:

2017 - Retina 5K 27"

8GB 2400Mhz DDR4

Thanks a mill!
