This is a problem that Linux cannot fix, but is a Windows compatibility issue. Windows compatibility issues are done by Wine, but not within Steam games as that is handled by Proton, which is a Wine-like compatibility layer. You will find that not everything that runs on Windows runs on Linux, even via Proton/Wine. As such, this is for the Proton developers to figure out within that github thread. This issue needs to remain in that conversation. There is nothing anybody working on Ubuntu can do about it.
