"Application permission: After updating to Big Sur 11.0.1 I get an error saying "you do not have permission to open the application …" when trying to run some (but not all) applications. What's going on? How do I get around it?"

Safe Mode:
Boot into Safe Mode, wait 30 seconds once logged in, shutdown the Mac, and then log in as normal. In Safe Mode, login items do not run, and corrupt system files(caches) are fixed. So, see if that fixes this. To boot into Safe Mode, hold down the shift key upon boot.
