Как пофиксить ошибку?

Question

[Bruh_Bruh]

Есть две сцены: меню и игра. Если из меню зайти в игру, то все хорошо, однако, когда заходишь в игру, потом возвращаешься в меню, затем снова в игру (2 раз), то вылезает ошибка, говорит что у меня там что-то удалено, хотя ничего не удалено. Ошибка: MissingReferenceException: The object of type 'PickaxeHolder' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
PickaxeHolder.RotatePickaxeToAveragePosition () (at Assets/Scripts/PickaxeHolder.cs:72)
ClickButton.OnClickButtonUp () (at Assets/Scripts/ClickButton.cs:21)
