After having many CTDs and error starting MSFS, I removed and reinstalled MSFS.
Now I can’t start it and get following error :
C:\Program Files\WindowsApps\Micrsoft.FlightSimaulator_112.13.0_x64_8wekyb3d…\FlightSimalator.exe
Thanks to all.
I reinstalled MSFS once again , deleted all MSFS files, and now starting OK.
I am still updating since yesterday so have not run it yet.
