Hi there,
Recently I can't open Illustrator, every time I try it, following dialog appears (I use Polish version so sorry if my translation is not spot on):
Failed to load translated resource files for this application. Repair or reinstall the app, then try again.
Reinstallation doesn't help, I suspect it might be the Big Sur update problem, what should I do?
The trick with deleting the com.adobe.illustrator folder from caches did not work.
