High Sierra disables Illustrator
Since updating to High Sierra last week every time I go to open Illustrator the spinning wheel appears and is never resolved. I chatted with support last week and was told I needed to contact Apple as it's a compatibility issue. They were also not able to help.
I have Ai 2015. It will open after the Mac OS 10.13.4 update but no features are available. Upon launching Ai a box appears saying that there is an error opening plugins (a long list). I can open files and go to Windows(tab) to open features and they appear to function. I have re-installed Creative Cloud and the manager (as suggested by the error messages). Nothing changes as a result.

Upgraded to High Sierra 10.13.3 two days ago on late 2013 Mac Pro. Spinning wheel and several crashes while within app until today when I clicked the Illustrator CC 2018 icon and nothing happened. Restarted system several times to resolve, no results. App will not launch.
