Had similar issue, my flightsim did not even start.
Steps that helped me.
- I’ve removed xbox app, removed all related msfs content (msfs uninstall, manualy removed all files left).
- PC restart
- Download xbox app
- Run installation from xbox app(there was a bug that total size was 150GB instead of 1.4gb installer)
- Moved to store, i’ve checked that msfs luncher is installed.
- Run msfs from ms store
- Nothing happend
- Closed and opened xbox app → run msfs from xbox app
- Sim has started and i’m downloading full content right now, it’s seems that it works well now.
Maybe you can do something similar.
