il2cpp::icalls::mscorlib::System::Array::FastCopy crash

I'm getting an issue where when I make a build using IL2CPP the build crashes without any useful information. This is even when I revert Perforce back to where I used to be able to make builds that ran OK, using the same Unity version that was previously successful. Last night I deleted the library directory, reimported all, reinstalled Unity, reinstalled Visual Studio, but the issue still happens. I can build and run a simple scene with only a sphere in it, but my actual game crashes. Any idea?

Unity 209.3.11f1
