Layouts “2 by 3”, “Tall” and “Wide” are empty. The editor is white with only the menu bar. From there I can add the views I want but they are not embedded into the editor; they are independent.
Furthermore, when I switch from one layout to the other I get these error messages:
from empty “2 by 3” to “4 split”:
Failed to destroy editor windows: #5
NullReferenceException: Object reference not set to an instance of an object
Failed to destroy views: #10
from “Default” to empty “Tall”:
Removed unparented EditorWindow while reading window layout: window #2 , type=UnityEditor.GameView, instanceID=10036
from empty “Tall” to empty “Wide”:
Failed to destroy editor windows: #4
NullReferenceException: Object reference not set to an instance of an object
Failed to destroy views: #9
Removed unparented EditorWindow while reading window layout: window #2 , type=UnityEditor.GameView, instanceID=10128
Known issue, working on it!
