amogus crashes if started through steam

[konradybcio]

Describe the bug
The game doesn't start (crashes after Innersloth logo fades out) if started through Steam. If the game is started directly (proton .steam/steam/steamapps/common/Among\ Us/Among\ Us.exe or similar) with steam NOT running, it starts up just fine, though without Steamworks access.

Steps to reproduce the behavior:

1. Open amogus through steam (library / through a gameid link)
2. It crashes (sus)
3. Open amogus directly
4. It doesn't crash

No crashes involved

Reproduced the crash but I'm not yet sure exactly what is happening.
Looks like the application's primary thread's stack vanishes which causes a cascading SIGSEGV. Will take some time to debug.
