Questions about editing the scene in Unity.

Hi, I tried editing scenes in Unity, and I copied a new object(a tomato) then place it on the table. I had the `GameMenu/SettlePhysics` done, and added the new object to the lists of `PhysicsSceneManager`. After built, I am able to pick up the copied object, and the `isPickedUp` attribute is also set to 'True', seems everything goes well. However, if I set the `renderInstanceSegmentation` as 'True' at the initialization of controller, then the simulator would crash, the error messages as follows:

Did I miss something in Unity settings?
