Почему в Unity возникает ошибка NullReferenceException: ссылка на объект не установлена ​​на экземпляр объекта в CameraS ⇐ C#

[Anonymous]

Ошибка началась после того, как я удалил из иерархии AIThirdPersonController.
Теперь у меня есть основная камера и ThirdPersonController.

У меня есть основная камера в Инспекторе i добавлен файл Camera Script.cs
