If i move any event in an animation i get this error:
NullReferenceException: Object reference not set to an instance of an object
UnityEditor.InspectorWindowUtils.GetFirstNonImportInspectorEditor (UnityEditor.Editor[ ] editors) (at <11d97693183d4a6bb35c29ae7882c66b>:0)
UnityEditor.InspectorWindow.GetInspectedObject () (at <11d97693183d4a6bb35c29ae7882c66b>:0)
UnityEditor.PropertyEditor.OnDisable () (at <11d97693183d4a6bb35c29ae7882c66b>:0)
UnityEditor.InspectorWindow.OnDisable () (at <11d97693183d4a6bb35c29ae7882c66b>:0)
UnityEditor.EditorApplicationLayout:InitPlaymodeLayout()

i searched for it and it should be an editor’s error but it pup ups exclusively after i move an event and click play. The event works perfectly fine if i leave it in its original place (it just enables player controls and two gameobjects). Like many said i already close all editors and reset layouts but nothing changed. I also deleted the event and remade it in a different time, same problem.

The event doesn’t work anymore when you get this error? The error seems to be in the Inspector window cleaning up, nothing that should impact the event itself from working.
