    Just upgraded to 2022.2 beta8.3023

    Calling .SetParent(null) during OnEnable results in this error message and failure to deparent:

    
Setting the parent of a transform which resides in a Prefab instance is not possible (GameObject: 'CameraGroup').
    
UnityEngine.StackTraceUtility:ExtractStackTrace ()
    
DetachOnEnable:OnEnable () (at Assets/+ProjectAssets/Scripts/Utility/DetachOnEnable.cs:7)



    The object in question is indeed part of a prefab in edit mode, but it is my understanding that prefabs are unpacked upon entering playmode and this should not be occurring.

    Looks like a regression because I do the same thing on 2020.3 and it works fine
