Hello @Zeph77, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/1006#issuecomment-830635611.
Apologies, $HOME/steam-$APPID.log file attached -

Symptoms
Hi, game runs perfectly but always crashes at the same point, right near the end of Mission 2 of Act 3. Graphics freeze but music and sound effects keep playing, and my computer locks up and needs to be rebooted.
I've tried removing all downloaded game content and reinstalling from scratch, and it does exactly the same thing at exactly the same time.
I submitted a help request to Steam and was redirected here with the following message -
_"All Steam Play & Linux issues are handled on GitHub at this time. Through GitHub, you can work with the development team & the Community to report bugs and request help with any issues you may be experiencing.
If you haven't already, please post any bugs or support questions in the GitHub below:

I'd REALLY like to finish this game, please help!. Many thanks.
