This is hopefully fixed in the current Proton Experimental ([bleeding-edge] branch, available to select in Proton Experimental properties, BETAS page).
Demo doesn't crash anymore!
And games against AI seem to work fine!
Thanks.

Symptoms
The game crashes after the first few greeting screens when opening the Terms of Service. Reproduction of the crash should take a few seconds.
The "nocrash" log is from exiting the game before clicking the Terms of Service button.
