Symptoms

Game executable (NS2.exe) appears to start but instantly crashes and runs its own built in error handler (SparkCrashHandler.exe).

Reproduction

• Use latest Steam client beta
• Force-enable Steam Play for the title in properties and use the latest Proton version.
• Start the game. It will appear as "running" but nothing else happens.
• Manually end the processes as they will continue to run until killed.

Note: This title does have a native Linux binary, but is mostly unsupported/maintained by the devs.

Start by reviewing steam-4920.log alongside the NS2.exe and SparkCrashHandler.exe launch sequence, then reproduce the crash using Proton as described. Done would require identifying a Proton-side cause and validating a fix or compatibility result for Natural Selection 2.
