[2023] Controller issues. [GamePass]

I see! Looking at the game in the Xbox app, it does not mention controller compatibility, so I'm not sure that's a supported feature anyway. If you have any sort of mouse cursor customisation active, such as mouse trails, try turning that off before starting the game.

I did see this product though which might help!
