I'm sorry you are experiencing any trouble right now. No worries, I'm here to help you. If I may ask, may I know which platform are you playing the game Forza Horizon 4 on, is it on Xbox Console or Windows PC?

Thank you for your response!

No worries, please try these solutions next:

Solution 1: Repair the game

Open the Xbox app for Windows.

In My Library, select the game title.

Select the More options (…) button and choose Manage.

Select Files and then Verify and repair.

Solution 2: Remove and reinstall gaming services.

Reinstall the Gaming Services app on your Windows 10/11 device:

Select the Search icon on the taskbar, type powershell, right-click on Windows PowerShell, and then select Run as administrator.

In Windows PowerShell, type the following command and press Enter:

get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers

In the same window, type the following command and press Enter:

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.

Restart your device and try to install the game again.

Solution 3: If this still doesn't work please proceed with the reinstallation of the game

If you're having trouble getting a game to play, uninstalling and then reinstalling the game might help. Occasionally, game files may get corrupted or altered, especially if you've had a malware problem or are running a game modification on your device.

Some games can even repair the original files without you having to remove the game completely. However, if you installed the game from the Microsoft Store, you'll only be able to completely uninstall and reinstall the game.
