Same problem with me, really annoying situation.

Anon, read the comments. I've been directly working with the Adobe team working on this. Sending them information and having screen sharing sessions for them to get to the bottom of it. They have posted, but it's not always clear when you first visit the page.

Can anyone from Adobe confirm that they are working on a fix for this? This seems like it's a big issue for many users and it's frustrating that you haven't posted anything. Makes me not want to use Adobe Creative Cloud at all. I know some bugs are hard to anticipate but 152 users have submitted comments on this bug so I think it deserves some attention.

Im getting that too. And now AI wont open files!!! I Cant work!!!! This is BS

Lo staff di adobe si è connesso diverse volte al mio windows (Windows 7 professional + service pack 1
64Gb a 64 bit - i7-6700 3.40 GHz - nvidia Quadro P2000 3Gb drive 24.21.14.1163), senza avere nessun successo, mi hanno cestinato le preferenze, fatto l'upgrade a CC2019, passato dalla preview GPU a CPU, aggiornato la scheda grafica, collegato stampante "Adobe pdf", ma è sempre la solita cosa, dopo alcuni minuti di lavoro va in crash!!!!

Since updating to 2019, this problem started to occur. "Can't create preview (not enough memory, RAM)" and Illustrator switches to artwork view. Tip: quickly save your work at this point, because the inevitable crash happens within a minute!

I work under MacOS Mojave, 10.14

Very serious impact to productivity on relatively simple vector illustrations.

macOS Mohave 10.14
MacBook Pro Late 2016
2.8 GHz Intel Core i7
16 GB RAM
AMD Radeon R9 M370X 2048 MB

Since upgrading to 2019 I am having the same problem too when working in Illustrator.

My specs for my mac is as followed:

mac0S High Sierra
10.13.6
Mac Pro (Late 2013)
3.7 GHz Quad-Core Intel Xeon E5
12 GB 1866 MHz DDR3
AMD FirePro D300 2048

The Illustrator file is 4.4MB and there is just one PSD image and the rest is vector based. I am working then the warning box comes up with 'Can't finish Previewing'. I click Ok and my artboard turns grey.

I use the keyboard shortcuts to zoom in and out and my artboard is still grey. I go to the View menu and click on GPU Preview but nothing happens.

I quit out of Illustrator and restart it and open up the same file (which is the recovery file), Save As. The artwork opens on Preview on CPU but on one occasion it still had the Outline preview.

This has happened about four-five times since the update.

Lost SO much work because of this (yes, I forgot to save, but Illustrator is supposed to account for that). Virtually unusable. Loved the new features, sucks I'm paying for something that doesn't work correctly. Will downgrade to CC2018 for now. Fix it quick!

After running the Illustrator program install/update three days ago, when I'm drawing shapes, Illustrator keep telling me that it cannot keep previewing the document and converts it to outline view. I have totally quite Illustrator and re-open it to restore preview functionality.

Unbelievable & Frustrating ASFK

Entire team is about to roll back to old version, because this issue... It sucks

It's absolutely unusable, I had to come back to the previous version. It's too bad because some new features are very nice.

Been experiencing similar issues...Can't finish Preview and its a simple file that i am working on, nothing major. These programs need to be tested PROPERLY before releasing new updates to clients that PAY for this software...very frustrating.

I have the same problem. Just out of the blue, I get the comment cant stop preview mode. I have to restart the program to get illustrator to stop preview mode.

Same here. It keeps crashing even on a very simple artwork.
Just rolled back to 22.1.

I updated this morning and have been experiencing the same thing. very frustrating

Illustrator keeps crashing with simple things and photoshop too.
Animated zoom (GPU Preview) keeps on failing.

Same problem. It takes a little bit longer but happens in the middle of work, have to save and restart. Annoying when I have a print deadline.

Twice v23.0 crashed when selecting layers, alert window approx says "Cannot perform preview" then my artboard disappears. I save to be safe, quit, then re-open same file. Artboard with sketch is visible but in CPU Preview. I never selected Preview on CPU or hotkey.
