Hello @MNS26, fragmenting the discussion of an issue across multiple issue reports is counterproductive. Since this issue report added a little more detail, I have transferred it to https://github.com/ValveSoftware/Proton/issues/6537#issuecomment-1806885326.
Closing in favor of the older issue report.
proton version: tested with 6.3 and newer
wine version:
