[Software] Assetto Corsa not working on Steam platform

[Fermark]

Hi, the thing is I'm trying to play Assetto Corsa on Steam using this new version of Kubuntu, but with no success. I just tried several proton archives (including GE protons) and nothing. Any help you can give to me in order to get functioning the game? The same with Forza Horizon 5, doesn't work at all.

Thanks in advance.
