Game doesn't accept input, leaving me stuck at the splash screen unable to play.

Hey there, 

There are a couple more things you can try to fix this: 

Delete/rename the hardware settings file:

• Navigate to:
  Documents\My Games\F1 24\hardware_settings
• Delete or rename the hardware_settings_config.xml file.
• This resets controller and graphics configs.

If the problem persists, please try to:

• Disable All Non-Essential USB Devices: Unplug all USB devices except your controller and keyboard/mouse. 
• Try Launching with Only Keyboard First: Launch the game with no controller connected. Once past the splash screen, plug in the controller.

Let us know how that goes,
