Double "Universal Additional Camera Data" in single Camera

Unity Engine
1

I keep having this problem. Where a camera that exists in a prefab dropped in the Scene the scene makes an instance of a second Universal Additional Camera Data which cannot be removed this causes the editor “Scene” window to break and not render anything. It also breaks playback gameplay in the editor.

I notice this happens only when the Scene Window is active in the editor. and I play test the game, if I remove the window and start the play test. i don’t get the error.

TEMPORARY SOLUTION: It seems like disabling “Post Processing” from the Scene window (top left icon ‘two layers stacked with a diamond on top’) fixes this bug.

I fixed this inside our project, the solution can be found here:
