Symptoms

Starting the game will create a ghost process that will hang around for about 15 seconds before terminating. The game window will never appear before the process terminates.

Trying to use the config tool spits out this error. This process has to be killed manually.

Reproduction

Just launch the game or the config tool.

Start by reproducing the failure by launching the game and the config tool with the reported Proton versions. Review the linked system information and Steam log for clues. Done means identifying and fixing the cause of the missing game window or hanging config tool, then confirming both entry points work.
