I can't install the games of my xbox on my pc.

Make sure the games you're trying to install support Play Anywhere, otherwise you'll need to buy them for the PC in order to play them on the PC. You may also want to try installing them from the Xbox app and not the Microsoft Store app.

I have exactly the same problem with my xbox pc beta, I have installed shadow warrior 2 included in my game pass then it started once, it didn't recognize the Microsoft xbox controller, the game crashed after a minute and since then it can't be installed
at all, starts installing and immediately tells me it's installed but I can't start it and it doesn't show up in the installed games.

Please try to check your game in the order history in this following website : Microsoft account | Home just to make sure that the purchase was through your account. However, if the game is in the account, I suggest to remove your account and add it back.
In case the issue still persists, please contact our live support Contact us | Xbox Support

Hi there,

not every Xbox One Game will be available to be installed on a PC.

Only the Xbox Play Anywhere titles will have the option to be installed on Xbox One and Windows 10 PC.

See this link with information regarding Xbox Play Anywhere and what games have that option:

https://www.xbox.com/games/xbox-play-anywhere

If the game supports Xbox Play Anywheren make sure you are using the same account that was used to purchase the game.

Let us know the results
