The FHE01 error in Forza Horizon 6 is a general crash code. It usually happens during splash screens, intro cutscenes, or right when you hit Start Game, crashing the game to your desktop. Here’s how to fix it quickly, step by step.

Alt+Tab Window Focus Bug (Fastest Fix)

A common launch bug causes the game to crash if the window stays focused during the startup sequence.

Steps:

Launch Forza Horizon 6.

Right after the Turn 10 logo disappears, press Alt + Tab to switch out of the game.

Wait 10–15 seconds on your desktop or another window while the game loads the main menu in the background.

Click back into the game to safely access the Start Menu.

This simple trick bypasses the crash caused by the game trying to render too quickly while focused.

Fix Controller & Steam Input Conflicts

Many FHE01 crashes are tied to controllers and input remapping software.

Tips:

Disconnect Peripheral Pucks: Remove any Steam Controller wireless dongles or virtual pucks before launching.

Disable Steam Input: Right-click Forza Horizon 6 in Steam → Properties → Controller → Override for Forza Horizon 6 → Disable Steam Input.

Clean Third-Party Drivers: If using a PlayStation controller, close DS4Windows or DSX to avoid duplicate virtual inputs.

Alternatively, unplug your controller, start the game with keyboard & mouse, then reconnect the controller after the main menu loads.

Clear DirectX Shader Cache

Corrupted shaders can trigger the FHE01 error during preload or after updates.

Steps:

Open the Windows search bar and type Disk Cleanup, then select it.

Choose your main drive (usually C:).

Check DirectX Shader Cache and click OK to delete.

Restart your PC and relaunch the game to rebuild clean shaders.

Throttle Graphics & Background Software

The Forza Horizon 6 engine is sensitive to overlays and GPU spikes.

To prevent crashes:

Close Performance Overlays: Shut down MSI Afterburner, RivaTuner Statistics Server (RTSS), Citrix Workspace, or any monitoring tools.

Disable Ray Tracing: If possible, turn off RT reflections and Global Illumination in-game.

If you can’t access the settings:

Use NVIDIA Control Panel or AMD Software to limit the game’s max framerate to half your monitor refresh rate.

Ensure GPU usage stays below 75% until a driver or game patch resolves the crash.
