Xbox App broken game installs

new xbox app (beta) is broken. first i first installed it, It showed no games owned. I still could play games installed, but had to search microsoft store for owned games. Now when I try the app it doesn't log me in at all. Broken App that messed up everything.
console app though bad at least worked.

It doesn't. I think it has something to do with not actually owning said games, but rather playing them through Game Pass. To me it's looking like an issue with the Xbox app and the beta version of the Microsoft Store included with the Windows 11 beta. Also of note is that the Microsoft Store won't let me buy the games, instead forcing me to buy them through the Xbox app if I wanted to do that. I'm going to make a bug report for the Windows 11 beta on this issue as well.

That's odd. I believe it's a bug. I haven't installed Windows 11 yet to avoid these bugs and getting ready to wipe everything before installing a clean copy.

No, just the two games in question. Killer Instinct is installing fine, and I can pause it from both apps, but I also own Killer Instinct, rather than through Game Pass. Pressing the button to go to the Xbox App makes the broken install appear again in the Xbox App. I can't end the install from the Store for the two games, the 3 dots are greyed out.

Look for the game in the store and see if the game page in the Microsoft Store shows the option to install without taking you to the Xbox app.
