Check Forza's known-issues page and the PC requirements first. Install current Windows, graphics-driver, store, and game updates, then test with overlays, FPS counters, monitoring tools, and other nonessential background apps closed. Verify or reset only the affected installation before reinstalling, and keep Event Viewer and DxDiag details if it still closes.
Open Forza's FH5 Known Issues page and look for the exact error or launch symptom. Record whether the splash screen appears and any Windows code. If the problem is listed as under investigation, keep the game updated and follow that entry.
2
Confirm the PC and installation drive
Compare the PC with the current Forza Horizon 5 requirements. Microsoft Store and Xbox app installations require an NTFS-formatted drive; an exFAT drive is not supported for that version.
3
Install current updates
Install Windows updates, the current graphics driver for the installed adapter, Xbox app or Steam updates, and the latest Forza Horizon 5 update. Restart after they finish.
4
Test without overlays and monitors
Close overlays, FPS counters, recording or streaming tools, overclocking software, input modifiers, and hardware monitors for one launch. These programs draw over the game or inspect it and can conflict even when their window is not open.
5
Check the correct store account
For an Xbox app or Microsoft Store copy, confirm the account that owns the game is signed in and the Gaming Services components are current. For Steam, start the game from the signed-in Steam Library rather than an old shortcut.
6
Repair before reinstalling
Use Steam's file verification or the Windows app's Repair option first. Avoid Reset until saves are synchronized and understood. If the game still closes, reproduce it once and collect the matching Event Viewer entry and DxDiag for Forza Support.
