Issues running with Wine 10.0

[MrJeremyFisher]

I'm having trouble opening the core settings tab when running with Wine 10.0 on Ubuntu 24.04. This occurs in the portable version as well which I was able to get working per #202 (switching to Wine 10.0). Looking at the source I see a flag(? pardon my terminology, I'm inexperienced with c#) for proton which seems like it would fix my error but to my understanding that's a preprocessor thing. Would I have to recompile with that flag set? If so how can I set the flag? The error I encounter is
