My xbox app will not launch

My xbox app will not launch, it shows a black window with the xbox logo in the middle and automatically closes after a minute. I have tried all trouble shooting steps given to me by the live "chat with a gamer thing". The app was directly installed from the microsoft store. Those steps included:
- repairing the xbox app
- repairing gaming services

- repairing xbox services

- clearing microsoft store cache with wsreset
- reinstalling gaming services and the xbox app

additionally, when downloading the xbox app, it downloads very slowly despite the app being very small. I have tried switching wifi networks to no avail.
I really just want to play my gamepass games, that's the only reason I want this app. What can I do?
