    Using 2020.1.2

    I get these warnings on every recompile of my game.
    It's coming from UnityEditor.SceneHierarchyStageHandling:StageHeaderGUI:

    My guess is you should also be checking
    (m_StageHeaderContent == GUIContent.none || m_StageHeaderContent == null)

    If you encounter this issue try opening a Prefab (double click a Prefab Asset) and then go back to the Scenes.

    This issue has been fixed in 2021.1 and backports have been requested.
