Bug UnityEditor.InspectorWindow.ShouldCullEditor: Nullreference

Unity version: 2019.3.0f6
Tested in: new clean project
Description:
I want to make a simple attribute that does "GameObject.GetComponent(...)" together with a property drawer.
My code to do this is correct but when I just create the property drawer I get the following errors (attachment)

Sidenote: This error displays almost everytime when I compile in another project so it is very annoying.

Error:
NullReferenceException: Object reference not set to an instance of an object
