I’d say that this looks like it translates to: System.Security.Cryptography.CryptographicException: Key not valid for use in specified state 
The solution for that part is described here:

  2. Restart Studio Pro.


As a side note, AppData is a hidden folder, so you should check the “hidden items” check box in your Explorer:
