Hi all,
I am having an issue with Illustrator 2021 that seemed to start up overnight. When I try to open Illustrator 2021 I get a "The operation cannot complete because of an unknown error. [CANT]" error message and then once it fully opens, it is just a gray screen and not the normal Illustrator interface. It does not respond to me trying to start a new file or save/save as anything I open. I can open previous Illustrator files and save as copy, but it is very frustrating to have to use these workarounds.
I have uninstalled and reinstalled Illustrator 2021 and restarted my computer. I tried clearing the cashes, but could not use any key commands when starting the program due to the error. I have to use 2021 because of certain plug-in licenses that are not compatible with newer versions, and I can't seem to convince anyone with authority at my company to upgrade them. I tried to use Adobe Support, but I guess due to my license being part of a company wide license for Adobe, I do not have the ability to go through normal support channels.
Any help is greatly appreciated!
