NullReferenceException

Hello, please can anyone help me with this error? I don’t know what to do with it.

NullReferenceException: (null)
UnityEditor.SerializedObject..ctor (UnityEngine.Object[] objs) (at C:/BuildAgent/work/7535de4ca26c26ac/Editor/MonoGenerated/Editor/SerializedPropertyBindings.cs:66)

I still can’t find a part of code, where is problem. I tryied delete one script by one, but still it writing this error

So you kept removing scripts until you had no script in you project and you where still getting errors?

No need to remove scripts to identify where the error occurs. The errors message in Unity editor tells you not only in what script but in what line it occurs - just as explained in the link provided.

I know, but it is a stupid. When i delete all scripts, i still getting this error.
And Unity editor says error is on these scripts: SerializedPropertyBindings.cs, AssetImporterInspector.cs, EditorBindings.cs, ModelImporterModelEditor.cs

When you create a new empty project also?

In a new project no error… YEAH, I HAVE IT! Enough off and on Unity engine
