Having the worst time with this upgrade. Spent all morning trying to work around a missing plug-in issue crashing Illustrator non-stop and refusing to open. Finally got it to work by ignoring the fix and I think I'm only able to work in Safe Mode. Additionally, I can't open new documents unless I do the legacy File open menu, which isn't the worst work around but is slightly annoying. Any fixes for the missing plug-in issue? I do not use any third-party plug-ins.
Which plugins are reported as missing?
If it's a longer list, then maybe something went wrong when installing.
