Xbox app game installation stuck on "Preparing 0%"

you're so good man it solved my nothing!11

Try to restore the OS then mate:

Step 1: Click Update & security on the Settings page to continue.

Step 2: Click Recovery and click Get Started on the right to continue.

Step 3: Choose Keep my files to reset your PC.

Step 4: Read the subsequent messages and click Reset.

After the computer has restarted successfully, you have refreshed Windows 10.

How odd, have you tried to reinstall the gamepass app?

Hiya, I've followed your steps and Minecraft Dungeons continues to hang at "Preparing 0%" then disappears from the queue. MFS hangs similarly but then stops with an error code: 0x803fb107

Hello dear Gamer, first it's a pleasure to be able to help you today.

Hey mate, how are you today? Hope you're well.

So, let's try this, first, lest begin by restarting your PC.

Then, make sure your windows and all its services are up to date:

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 you're going to uninstall the games services using a powershell command, then you're going to open the gamepass app, it will ask you to download and install the game services again :

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, then open your Xbox gamepass app, it will ask you to install the gaming services again, install it and try again.

Hope this helps. Cheers.
