Heya Nitro,

.My names is Brian I'm an Xbox ambassador and I will try my best to share with you more info and methods to try and fix this...

.First let's completely clean your Xbox App and Microsoft store cache and your accounts cache. The steps below are similar to what you probably already have done:

- Uninstall Flight Simulator just as a test.

- Completely uninstall Xbox App (and Xbox Companion App if you have it). Use their own uninstaller (just search for Xbox on Windows Start and click on uninstall).

- After uninstalling, go to Start > Type PowerShell > Right click it and select “Run As Administrator” > Type the following command and press Enter (you can run one at a time):
Get-AppxPackage Xbox | Remove-AppxPackage
Get-AppxPackage Microsoft.XboxApp | Remove-AppxPackage
Get-AppxPackage Microsoft.GamingServices | Remove-AppxPackage –allusers
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

(If you receive an error when executing any of these commands, don't bother. Just follow the other steps here)..

- Press Windows + R and type in "regedit". Press enter.

- Search for HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services

- Delete the folders "GamingServices", "GamingServices.net" and "xinputhid" (if they're still there).

- Click on Start > Credential Manager > Windows Credentials. Search for Xbl|DeviceKey, click on it and then Remove.

- Delete Accounts and Cache folders at:

C:\Users\Username\AppData\Local\Packages\Microsoft.XboxIdentityProvider_8wekyb3d8bbwe\AC\TokenBroker

- Also delete Microsoft Store local cache files at:

C:\Users\Username\AppData\Local\Packages\Microsoft.WindowsStore_8wekyb3d8bbwe

- Go to Start > Settings > Apps > Apps & features > Microsoft Store > Advanced Options > Reset.

- Go to Start > Settings > Gaming > Xbox Networking > Fix it.

- Go to Start > Settings > Gaming > Game Mode > Set if OFF.

- Go to Start > Settings > Accounts > Sign-in Options > Privacy > Uncheck "Use my sign-in info to automatically finish setting up my device and reopen my apps after an update and restart."

- Press the Windows Key + R. Type WSReset.exe and press Enter.

- Restart Windows.

- If you're using a proxy, please stop using it for now:
- Press Windows Key + R. Type inetcpl.cpl and press Enter. Click the Connections tab, and then click LAN settings. Uncheck the Use a proxy server for your LAN check box. Click Ok.

- Please check if Date and Time is set correct. Uncheck "Set the time automatically", do it manually.

- Run PowerShell as an Administrator again and run the command:
start ms-windows-store://pdp/?productid=9MWPM2CQNLHN

- Install the app on that page and select Yes when you receive the User Account Control (UAC) prompt. Make sure you are signed in on the Microsoft Store with the correct Microsoft Account.

- Finally, install Xbox App (and Xbox Companion App if you had it) again. Open it and login to the correct Microsoft/Xbox account. If you are on the Xbox Insiders program, click on the profile image and navigate to the settings menu. Head over to the General sub-menu in the Settings menu. Uncheck the “Use advanced installation and management features” option. If this option was checked, please restart your computer.

- Try to install the game that you uninstalled on the first step. See if it works and please let me know. If it does not work, I'd suggest you to create another local account on Windows and install the game there.

. If that didn't work then I recommend contacting live support and try there:

Going to add to this. Having the issue on MSFS 2020 and Teenage Mutant Ninja Turtles Gamepass games. Same error code, reinstalling does not fix it. Tried repairing the windows store and reinstalling game services to no avail.

This worked for me!!!

"on xbox app for pc click on 3 vertical dots ,create a shortcut on desktop , right click shortcut , run as administrator , worth a try"
