Hi Bn-,
Thank you for reaching out Microsoft Q&A and sharing the details of your experience with The Alters on the Xbox PC app. I understand how frustrating it must be to encounter launch issues, especially after everything was working smoothly before. I truly appreciate the time and effort you've already invested in troubleshooting.
Based on your description, it sounds like you've taken all the right steps: reinstalling the game and app, verifying files, updating Windows, and even checking memory diagnostics. It's great to hear that your save file remains intact when streaming via Game Pass, and that other games are unaffected.
Given the complexity of the issue and the fact that it seems isolated to The Alters, I recommend contacting the Xbox Support Team directly. They have access to deeper diagnostics and can investigate potential account sync issues, DRM conflicts, or game-specific service disruptions that may be affecting your setup.
