Let's 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 (Install optional updates as well)

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

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 that doesn't work, try creating a new NTFS partition on your external drive and see if Xbox app recognizes it

**Remember change where new apps are going to be installed inside windows settings

Hi GivenUnicycle60, I hope you're doing great out there despite the issue that you're experiencing. I am an Independent advisor and I am here to help you in regards to your concern.

On your Xbox App kindly install the Forza Horizon 5 Premium Add-Ons Bundle, simply search for it from there for you to have an option to install.

If it's already installed kindly repair the game and then restart your PC.

Settings > Apps > Search for "Forza Horizon 5" > Advanced Options > Repair > Restart.
