It sounds like you are using Python 3.11.2 or newer.
That version of Python cannot be used with Chromium's mojom scripts until https://crbug.com/1422178 (which I reported 4 months ago) has been fixed.

public enum Hello
{
Hello
}
public class C
{
public Nullable<int> M(Nullable<Hello> hello)
{
Nullable<Hello> hello2 = hello;
if (!hello2.HasValue)
{
return null;
}
return (int)hello2.GetValueOrDefault();
}
}
