And then go to the Microsoft Store, select More > Downloads & updates > Get updates.

Update everything in both places, and let me know if it works

Tell me what appears in this test please. Download the companion xbox console app > settings > network > NAT type

And connectivity

Right click on the Start Menu icon

Select Windows PowerShell (admin)

On the screen that opens, type:

Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

(make sure you don't leave any spaces before or after the command) and press Enter

Wait for the process to complete

Restart your PC

See if the problem persists

I remain at your disposal if you have any further questions.

Before reinstalling the game, try this:

Open Settings, click Update and Security and then Windows Update;

Click Check for Updates;

Click the Download and Install Now option, if available;

Then try this:

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

After that click repair and then restore, open the app and try again.

If it still doesn't work:

In the windows search bar type Powershell > Right click and select open as administrator > Type the command: "get-appxpackage Microsoft.GamingServices | remove-Appxpackage –allusers" > Wait for the process to finish and then restart the PC and try again.

Check for updates on Windows Update and install all updates including optional/additional updates.

These steps can help you too, give it a try.

1. Logout from Xbox app and Microsoft Store app

2. Look for the Xbox app and Microsoft Store in the Windows bar, right-click, click app settings and then click terminate, restore and reset. Do this with the game too.

3. Clear the store cache type ''wsreset'' in the Windows bar, run as admin, and wait for the screen to close and open the store automatically.

4. Login with your account again in both apps

5. Open the Microsoft Store, click on the 3 dots in the upper right corner ''download and updates'' and click on ''get updates'' and update everything. After these steps try again.
