So i have been having launch issues with the Xbox Game for PC and chatting to microsoft support we migjht have solved my issue maybe this will help you.

 

1 Make sure you have an outlook account for game pass and microsoft store as my hotmail account might have become corrupted

2 uninstall MSI afterburner

3 uninstall latest updates as they might be unstable

4 opt out of insider preview could potentially create conflicts

5 reinstall game ready driver but only what you actually need

6 set graphics priority to high

7 set priority in task manager to high for the game and the xbox app and game bar

8 uninstall bloat software that come with some necessary software like i have aurora but i didnt need the ram install software

9 reset windows get clean install then do all the above so apologies here this should be number 1

 

I think about covers 2 days worth of speaking to 4 different techies

 

fingers crossed i have had no crashes at all

Just wondering if this did solve your issue and if you had zeroed down for your case what caused the game to crash.
