I've tried sign in/sign out, refresh license.
Everything was fine with V81, then I updated to V83 and this bug happened. What should I do now?
I hit this problem last night after updating two projects. It worked fine in one and failed with this bs on the other. So I threw in the towel and went to sleep. I think there was a pending OS update on my system also. Woke up today and I don't see this error anymore.
So I guess my expert advice today is : try turning it off and turning it back on :D
