Hi Kenura, you have to make sure that the main menu has a build index of 0 (that’s the number beside the scene in the build settings):
If it is not 0, you will have to update the number in your DestroyInMainMenu script (see highlight below) accordingly.
public class DestroyWhenInMainMenu : MonoBehaviour
// Update is called once per frame
if(SceneManager.GetActiveScene().buildIndex == 0)
