Running through proton leads to crash (Could not resolve type)

[bicobus]

Running the launcher (not Ex), will properly start the game. But it crashes before reaching the main menu. LauncherEx crashes right away.

The runtime on with the game runs on linux is Mono, not the .NET Framework. Could that be a cause?

Don't have access to a Linux right now, but it looks like for some reason some of the MonoMod assemblies are loaded with the wrong version
