Injected fields returning injected types cause a crash

If you do the following

[BepInAutoPlugin]
public partial class TestPluginPlugin : BasePlugin
{
    public override void Load()
    {
        ClassInjector.RegisterTypeInIl2Cpp<MyBehaviour>();
        ClassInjector.RegisterTypeInIl2Cpp<MyTestObj>();
        
        MyBehaviour myBehaviour = new GameObject().AddComponent(Il2CppType.Of<MyBehaviour>()).Cast<MyBehaviour>();
        MyTestObj myTestObj = new GameObject().AddComponent(Il2CppType.Of<MyTestObj>()).Cast<MyTestObj>();
        myTestObj.myBehaviour.Value = myBehaviour;

        MyTestObj myNewTest = Object.Instantiate(myTestObj).Cast<MyTestObj>();
        Log.LogMessage("myNewTest.myBehaviour.mySpriteRenderer: " + myNewTest.myBehaviour.Value);
    }
}

public class MyBehaviour : MonoBehaviour
{
    public MyBehaviour(IntPtr ptr) : base(ptr) { }
    
    public Il2CppReferenceField<GameObject> mySpriteRenderer;
}

public class MyTestObj : MonoBehaviour
{
    public MyTestObj(IntPtr ptr) : base(ptr) { }

    public Il2CppReferenceField<MyBehaviour > myBehaviour;
}

The game will crash once you call Object.Instantiate(myTestObj)

Though, if you switch the return type to be something more generic i.e MonoBehaviour in myBehaviour, it works fine
