I tried to reboot to Windows 10, and the game than updated and started successfully.

@Mooling This error code describes a file copy failure,. That indicates limited write access to the drive. I assume the game is installed on an NTFS partition, in which case I would recommend you to check the following wiki article on how to properly mount the drive on Linux: * https://github.com/ValveSoftware/Proton/wiki/Using-a-NTFS-disk-with-Linux-and-Windows
