In case you're having proton issues.

This took me a second to figure out hopefully this helps someone else. In case you're having issues getting this game to launch with proton and you also happen to be running an Nvidia GPU I might have the solution. Try to launch the game using Proton Experimental and the following in your launch options (without the ""): "PROTON_HIDE_NVIDIA_GPU=1 %command%". Have fun cleaning that cash!
