Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Calin

Please try and double check this:

Open Settings, click Update and Security and then Windows Update
Click Check for Updates

Click the Download and Install Now option, if available (Install optional updates as well)

Also, check the Microsoft Store for any updates on the Xbox apps and its services and update everything too. (Click on get updates)

Now, sign out from your account on both Xbox app and Microsoft Store and do this:

Go to windows settings > apps > search for gaming services app > click on it and select advanced options.

After that, click repair and then reset

Then do the same for the Xbox app:

Go to windows settings > apps > search for Xbox app > click on it and select advanced options.

After that, click repair and then reset

Finally do this:

Step 1: Open the Run window by pressing Windows + R key.

Step 2: Input WSReset.exe in the Run window and click OK.

Step 3: Then a command prompt window will appear. After a few seconds, Windows Store will open.

Sign in again on both Microsoft store and Xbox app with your account and try again

If maybe the issue persist, try this instead
Reinstall Gaming Services using powershell command

Press Windows key + X and then select Windows PowerShell (Admin).

Type or copy / past the following command and press Enter:

Get-AppxPackage *gamingservices* -allusers | remove-appxpackage -allusers

Restart the PC and Open the Xbox application.

A blue notification with the following message is going to appear at the bottom:
"This app needs an extra component. Gaming Services is needed for playing some games. Administrator approval required. Install"

Select Install to reinstall Gaming Services, once installed check again

Here all games reverted to normality after a while.

I think it solved the problem when my pc used the microsoft store app to install/uninstall the games instead the xbox beta app, maybe you can try it

Try to install it from the Xbox app, if you don't have the Xbox app installed on your pc, install it from the Microsoft store.

- If that doesn't solve the problem you will have to contact game support as this is not supposed to be happening.

Delete your Xbox App Pc Beta , update windows, Install Xbox App Pc Beta again, login and check if it solve.
