Fix Forza Horizon 6 Steam Says Running But Game Is Not Launching On PC

If Steam says Forza Horizon 6 is running but the game is not launching, this guide will show you a few simple fixes to try.

This issue can be really annoying because Steam acts like the game has opened, but nothing appears on your screen. You might click Play, Steam changes to Running, then Forza Horizon 6 never opens. Sometimes it may sit in the background, close after a few seconds, or stay stuck in Task Manager without showing the game window.

This can happen because of a Steam cache problem, broken game files, stuck background processes, DirectX shader cache issues, overlays, antivirus blocking the game, or Forza Horizon 6 not launching properly through Steam.

Clean Graphics And DirectX Shader Cache With Easy Gamer Utility

You can also clean your graphics card cache and DirectX Shader Cache with Easy Gamer Utility.

These cache files are used by Windows and your graphics driver when loading games. If they become corrupt, Forza Horizon 6 may get stuck launching, show a black screen, crash on startup, or sit running in Steam without opening properly.

The first launch after clearing the shader cache may take a little longer. This is normal because Windows and your graphics driver need to rebuild the cache again.
