You can enable a mode for the Proton Experimental Version, where you get always the lastest fixes and new features. But it´s possible too, that there are bugs. I never had problems with it and it´s working sometimes much better on newer games.
At first search in the Steam Deck for Proton Experimental and enter it:
Than go to the settings:
Than go to „Betas“ and select: „bleeding-edge – latest untested dxvk, vk3d-proton and wine changes“
