Hey everyone,
I just moved from xbox to PC. Clean install.
I was facing the issue too and I was unable to solve it with the suggestions provided in this thread. What worked for me was deleting the fs-base-ingamepanels-metar folder located under
C:\Users\<YOURUSERNAME>\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages\Official\OneStore
