Meta XR All-in-One V83 Error License

An error occurred: This package isn't available because its
license isn't registered to your user account. If you're
licensed to use this package, go to Unity Hub >
Preferences > Licenses and click Refresh. Otherwise,
contact your administrator.

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
