Compiling the main library will trigger the error

I have a netstandard library (CompilerCrashRepro) that references another netstandard library (Dependency). In Dependency, I have the following struct defined:

    public struct Configuration
        private string path;

When I try to create a new instance of Configuration in CompilerCrashRepro, I get "Error CS0584: Internal compiler error: Unexpected error when loading type `Native.Configuration' (CS0584) (CompilerCrashRepro)"

If I remove the [MarshalAs] attribute or make the field public, the error goes away.

I've attached a minimal repro.
