I switched back to the 2018 version because I was experiencing this problem as well on a MacOS High Sierra 10.12.6.

I rolled back to the 2018 version also. Following this and other threads for updates.

Same problem ever since 2019 version came out.
MacOS 10.14 Mojave
Late 2014 iMac 27"
4Ghz Quad-Core i7
32GB RAM
AMD Radeon R9 M290X 2GB
2TB Scratch Disk

I'm having the same issue. Just updated to the latest version last week and I've had this happen several times. Not on a super complex image with a million tiny vector nodes, jut basic stuff that shouldn't be taxing the system. I'm usually able to save the file, but it immediatley crashes after that and is difficult to restart.

Mac High Sierra Version 10.13.3
memory: 16 GB

bump.

this has happened to me as well with the latest version of illustrator on creative cloud (cc v 23.0). i reinstalled cc v 22.1 and everything is back to normal and not having this issue

Got the same problem on MacOS High Sierra 10.13.6 after downloading newest Illustrator CC.

Got the same problem on one of our Macs (2013 MacBook Pro 13-inch, 2.8GHz i7,, 16GB 1600MHz DDR3, Iris 1536MB running 10.13.6). Got 3 other Macs running Illustrator and haven't had the same issue on those yet.

same here. iMac Mojave.
have to use it for work! please fix it asap.

Anyone experience this? Solve this? It is happening to me as well.

Yes, this is happening ALL the time for me too! Is there a fix?

Same problem here! Fix this bug!

After around 10 minutes work on a file - and I'm working on a simple design for a logo, the screen turns grey and a message appears saying 'Can't Finish Previewing.' The it crashes and quits.

This has happened at least a dozen times in the last 24 hours.

I've restarted, uninstalled and reinstalled Illustrator 2019. I've deleted temp files. I've created a new, clean file and still it is happening.

I'm on the latest OS X.

I couldn't take it anymore. I finally rolled back to v22. Just gonna hang tight until they fix this.

Stesso problema anche da me in fase di apertura file.

24GB iMac 27" - ridiculous failure on the simplest of files.

Same problem!

Finally got a crash on macOS. It happened after trying to keep on working even after I was forced into outline mode. Please find as a text file under the following link – https://www.dropbox.com/s/9at0gshbv3w464g/Adobe%20Illustrator%2023%20crash%20raport.txt?dl=0

having same issues for me

Same problem! Very annoying.

Half way through a simple task in Illustrator CC 2019, all my work switches preview to "outline" and an error message keep showing: "Can't finish previewing."

This really sucks!

This version is RUBBISH!!!

Better switch back to CC 2018.
