Reinstalled Windows but XBOX (BETA) app doesn't detect my games anymore.

it won't, you have to reinstall all the games, its a pain but its how they have done it. no other way around this. it is a royal pain. steam and all the other can be done but gamepass and windows store installs, nope.

Same problem here.

And no Reinstalling Windows or Deleting my connected Account is not a solution.

Especially considering that "Xbox Console Companion" is perfectly fine to login to my Account and show my games at the same time.

Tried uninstall and reinstall the App, same problem persists.

It let's me login, it seems to detect me properly, but than the app act's as it doesn't know me.

try either reinstalling the xbox beta app, or try to download the game using the Windows 10 Microsoft Store App

Hi, no luck yet.

I already installed the game on another drive yes. It was on d: now on c: Same problem on both drives.

I followed all your instruction including deleting the Xbox Identity Provider app through the powershell.

I can't reinstall the app though. It doesn't show up in the windows store. If I follow your link and click the get in store button it opens the windows store but doesn't show anything or if I already have the windows store open it just activates the window but stays on the same page. If I search for Xbox Identity Provider in the store itself i can't find anything.

So at the moment my xbox app doesn't work at all anymore (only a black screen with an xbox icon). Reinstalled the app itself but that didn't help.

*edit*

so i ended up reinstalling windows, that fixed all the problems. Xbox app launches again, first game i installed was deathloop and that launches now as well

you should try to either reinstall the xbox beta app, or try to download the game using the windows 10 app store
