✅ ImmutableArray<T>.Contains(T, IEqualityComparer<T>) exists in one thread, but not another

this is a very confusing problem and i have not had any luck producing a minimal working example; i'm happy to provide any kind of info. i'm making a mod for a game (Celeste) that involves compiling and loading C# source at runtime; i'm using Microsoft.CodeAnalysis.CSharp for this. i already have a standalone prototype of that process and am trying to convert it into a mod. for some reason, only in the mod version, when i call CSharpCompilation.Emit , an error is thrown in the worker thread:

System.MissingMethodException: Method not found: 'Boolean System.Collections.Immutable.ImmutableArray`1.Contains(!0, System.Collections.Generic.IEqualityComparer`1<!0>)'.
