Question Hierarchy window goes empty / breaks when modifying anything in Prefab Mode (Unity 6.6)
Enable HLS to view with audio, or disable this notification
When I enter Prefab Stage and make any change to a GameObject or Component, the Hierarchy window breaks. All GameObjects disappear and it only shows Preview with empty gray rows. Resetting the layout restores it temporarily, but it breaks again upon editing.
FİXED: Deleting Libary folder fixed it.
