The referenced script (Unknown) on this Behaviour is missing!

Hello, I Saw similar question on this forum, but nothing worked. I made a game with unity 2020.2.6f1 and since yesterday, my console shows this warnings:

The referenced script (Unknown) on this Behaviour is missing!

The referenced script on this Behaviour (Game Object ‘’) is missing!

The referenced script (Unknown) on this Behaviour is missing!
UnityEditorInternal.InternalEditorUtility:GetGameObjectInstanceIDFromComponent(Int32)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

The referenced script on this Behaviour (Game Object ‘’) is missing!
UnityEditorInternal.InternalEditorUtility:GetGameObjectInstanceIDFromComponent(Int32)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

i tried to dobbleclick them but when i do this a empty script called SceneHierarchie.cs opened which i didn’t created.

I hope someone can help me and sorry for my bad english.

thanks

Whatever gameObject is called "Game Object " has a missing script, probably you deleted it

If you didn’t create it, did you use a new asset/package recently?
Is the error shown before you press “Play” or during play mode?
