I have been having problems with various 3rd-party apps (BBEdit, MS Word, etc.) randomly crashing on launch. Instead of the app opening up normally, I get a dialog box saying I do not have permission to open the app followed by the crash log window. I contacted BBEdit support about their app crashing, and they said it was a code-signing failure and that the system just "hiccuped" (their term). Rebooting does not help. The crashes do not occur all the time, just at random. I am running Big Sur 11.0.1 on a 2017 MacBook.
