Today i discover that steam games were a few proton versions short so i went to the proton+ app to check, the proton GE latest needed an update but got an error message "Cannot update, unknown error" or similar. Decided to update and upgrade my system to try to solve it but after a reboot every game gets me an error message with dx12 and won´t start. Also my Nvidia drivers (580) are not usable anymore. Got to go back to the recommended driver (535) to get it to work again.
Any advice on how to solve this?
