Same problem here, had to go back to v22.

I have the same problem. Wow, this is annoying!

I don't know if anyone else has noticed it, but I have the most problems when dealing with "Live" type.
The program is somewhat slow in response to anything dealing with type.
When using outlined type or regular objects, the program is much more responsive.

MAC: Mojave using Font Agent (latest version).

while they are fixing this, can they please add an autosave feature???

Illustrator is running out of memory in the newest version. Although I work on files with 2 MB size and have enough RAM (16GB) on my MacBook Pro, Illustrator occasionally comes up with "not enough memory" and prevents me from opening a file

Newcomers, Adobe has emailed me. They are working on fixing this. Just commenting to all the new commenters that have voiced their concerns as well. Looking forward to the coming fix.

Same issue here. Fails to preview and sometimes crashes as well.

Same thing - Mac OS Mojave - iMac Pro 128GB ram - brand new install etc. Illustrator crashes after 15-20min and the same error. Have to quit everything and relaunch AI.

Having the same issue. Just updated to 2019 a couple of days ago. I hope this will be fixed soon.

Same problem with Illustrator crashing. Need fix ASAP...

having the same issue. Not crashing every time, but unable to preview so I have to restart.

same to me. german version on windows. cant work anymore....

I uninstalled 2019 and reinstalled 2018. Just cannot work efficiently while having to restart the software all the time. But thank you Kyle for sharing that they're working on it for us!! I'll just wait until they, hopefully, fix the bugs, and then maybe reinstall 2019.

Hey everyone. I just received this message late last night (PST) from Anish Kumar from Adobe:

"Thanks everyone for the response and your willingness to help. We are able to reproduce the issue inhouse and are working on it.

I will get in touch with you in case we need any help from your side.

Thanks
Anish"

So we will be getting a fix soon. For now, I'm just going to hang tight and keep rapidly saving, quitting, and re-opening Illustrator to work around the issue.

Experiencing the same problem here after updating to Illustrator v23... "Can't finish previewing| and then it crashes.

I'm on:
• macOS Mojave
• iMac (Retina 5k, 27-inch, Late 2015)
• 3.2 GHz Intel Core i5
• 16GB 1867 MHz DDR3

Experiencing the same problem here too "Can't finish previewing" since updating to v23.

I'm on:
macOS Mojave
iMac (5k, 27-inch, Late 2015)
3.2GHz Core i5
16GB 1867 MHz DDR3

Exactly the same problem here with AiC2019 (v23): do anything, dialog appears saying “Can't finish previewing”, and in a short time I suffer an Ai crash.
