I confirm:

• that I haven't found an existing compatibility report for this game.
• that I have checked whether there are updates for my system available.

Symptoms

With official proton versions 5.0, 5.13, Experimental the demo will crash with the Unity crash dialog when loading a New Game.

With Glorious Eggroll's Proton-5.21-GE-1 the demo loads successfully and the demo is fully playable.

EDIT: I realised after the fact by watching youtube playthroughs of the demo that there's supposed to be an intro video playing. But even Glorious Eggroll's proton does not show it properly, only displaying a black screen.

I've generated proton and dxvk logs with the different proton versions to maybe pinpoint the things that need to be implemented or fixed in the official proton to make the game fully playable. Again, the demo is fully playable with Glorious Eggroll's Proton 5.21-GE-1.

Hello @popsUlfr, looks like this demo would benefit from support for Media Foundation maturing. Specifically, fixme:gstreamer:DllGetClassObject {62ce7e72-4c71-4d20-b15d-452831a87d9d} not implemented, returning CLASS_E_CLASSNOTAVAILABLE. looks like a line of interest from the log which appears to be related to H264 video decode.

Thank you! So I actually realised by going on youtube and watching people play the demo that there's supposed to be a little intro video when starting a New Game. This means that even Glorious Eggroll's proton does not show it properly.
I applied the media foundation thingy that shall not be named to the official experimental proton and this makes the demo load properly without crashing but also without properly showing the intro video.
