How to Fix Infinite Loading Screen
If you are stuck at the loading screen after optimizing shaders, chances are the xbox sign-in never appeared to link the game to your account.
Following these steps will fix that problem.
On the Windows start menu, search for ‘Credential Manager’.
Click on ‘Windows Credentials’ on the upper right side.
On each credential that begins with ‘Xbl’, click the drop-down and select ‘remove’. These credentials will be created dynamically as every game you play will automatically generate them as needed.
After removing all of the credentials, Start Forza Motorsport again and you will see the sign-in splash screen. Sign in with your Microsoft Account and enjoy the game!
One-click solution (much faster!):
Open notepad, paste the following into Notepad and save as: remove_credentials.bat and then double-click the file you saved to run it. After it is finished, start up Forza Motorsport.
@echo off cmdkey.exe /list > "%TEMP%\List.txt" findstr.exe /C:"Target: LegacyGeneric:target=Xbl" "%TEMP%\List.txt" "%TEMP%\tokensonly.txt" FOR /F "tokens=1,2 delims= " %%G IN (%TEMP%\tokensonly.txt) DO cmdkey.exe /delete:%%H del "%TEMP%\List.txt" /s /f /q del "%TEMP%\tokensonly.txt" /s /f /q echo All done pause
