I guarantee you that Xbox GamePass tech team is not reading this lol. Not because they don't care, they probably could help you, but because Lemmy is literally a super-minority platform. Same reason they aren't in forums like zenhax or se7ensins.

Did you check the %LOCALAPPDATA%?

Also this happens on steam frequently as well, speaking from experience.

Stop whining here and contact Microsoft before their next database backup job runs.
