[ModApi] Exception thrown on IMyMotorStator.AttachedEntityChanged event handler register

When we try to register an event handler for IMyMotorStator.AttachedEntityChanged, an exception is thrown:

Cannot bind to the target method because its signature or security transparency is not compatible with that of the delegate type.

The same exception is thrown on IMyLandingGear.LockModeChanged

namespace Test {
    [MyEntityComponentDescriptor(typeof(MyObjectBuilder_MotorStator), false)]
    public class StatorLogic : MyGameLogicComponent {
        private IMyMotorStator _stator;

        public override void Close() {
            _stator.AttachedEntityChanged -= OnAttachedEntityChanged;
        }

        public override void Init(MyObjectBuilder_EntityBase objectBuilder) {
            _stator = Entity as IMyMotorStator;
            NeedsUpdate = MyEntityUpdateEnum.BEFORE_NEXT_FRAME;
        }

        public override void UpdateOnceBeforeFrame() {
            _stator.AttachedEntityChanged += OnAttachedEntityChanged;
