Works out of the box if you revert to Proton 7.0-6 and remove the prefix. Meta Quest 3 via ALVR. Did not work through WiVRn.

Apparently it doesn't work anymore, at least on current proton.
Still have to do more tests, but it's possible that the anticheat stopped working.

Did "launch" but nothing happend
Doesn't work out of the box I'll see if I can make it work :D
I am using 2 vive wands as controllers, sometimes for example when a meeting is called the controllers won't stop vibrating until something else makes them vibrate, for example pressing the buttons on the vending machine in the cafeteria, I don't know if this is linux only, or even vive only

PROTON_NO_ESYNC=1 %command%
strange VR distortion that was fixed by adding PROTON_NO_ESYNC=1 %command% line
strangely playable after adding some command line parameters, I will try to tweak it more
I use Proton GE just in case, but that doesn't mean you need it. It might work fine with the recommended version. Regardless, I've experienced zero issues with this game.

Works out of the box. Using Valve Index.
I had had some issues with matches disconnecting in the middle but according to the forums that's the same as for windows players. There doesn't seem to be any anti-cheat getting in the way specifically for Linux.
