Changed motherboard without uninstalling XBOX Game Pass first and I'm stuck and can't use...

Answering to myself in case somebody search for a solution to how to delete the WindowsApp:

I booted using an USB key with Windows 10 installer (made through MediaCreationTool from Microsoft) and when first windows appear asking if I want to install Windows 10 I used Shift-F10 to open a command shell. I guess you can get to this point using simply
Safe Mode boot. Then from here I was able to navigate to my d: drive and type :

rd WindowsApps /S /Q

Et voila! Ciao WindowsApps.

I reinstalled XBOX Game pass PC, Reloaded MSFS2020 installer (1GB) and then it asked me where to install its package, I gave d:\Games\FS2020 and it checked this directory for few minutes, downloaded nothing more, and launched the game.

Resolved

I play on my phone with the game pass app, and i can't manage my mods without launching the game.

And when i launch it crash... I'm stuck

First check if the games are still in Game Pass https://www.xbox.com/en-US/xbox-game-pass/games

If they are, then uninstall them and reinstall from Game Pass, that should clear the error.

same issue ... can't update any xbox game pass PC games....

have to uninstall /reinstall.

other apps (that are not xbox game pass) are uptated through store without any issue.

for microsoft: dead cells has no cloud saves through xbox live (working on outer world/gears 5..but not dead cells)
