MacOS Catalina > App Store freezes and hangs while starting
At some point (didn't notice if there was some specific update or any other event that happened before) I could not open App Store any more. I have tried everything I have found on the net - emptying caches, resetting network, changing date, signing in and out with my Apple ID, booting in safe mode - nothing works. Any ideas how to troubleshoot what is causing this?
I am on 10.15.2 MacOS Catalina
