Splitgate 2 opened the public beta since today or yesterday. Unfortunately the game does not run on desktop PC with a Linux operating system. Others have the same problem.
But whats weird is, people claim it works on Steam Deck and even the official blog post from the devs says they support the Steam Deck. There is no word about general Linux desktops.
So does the developers treat the Steam Deck like a console and make their games not playable on general purpose Linux desktops? Its weird, because otherwise it is playable on a general desktop with Windows too. Even the previous game Splitgate 1 (which they shut off) worked on desktop Linux. It makes no sense!
I’m totally disappointed right now. Because I was excited for this game. It got some hero abilities (I like that) and even a map creator.
Proton github has a possible workaround.

I wouldn’t experiment with renaming or deleting such files to trick an anticheat tool. There could be a potential to flag and ban a player account. It’s too risky to me.
You could also point Steam custom launch command to PortalWars2Client.exe and leave the files as is, but I suppose you still could be banned.
