Question Can't build more than once per Unity Version due to prefab error

Hello, I am trying to iterate with my game builds however I can't build more than once.
I get these errors:

Error removing component when merging Prefab changes: Can't remove Camera because HDAdditionalCameraData (Script) depends on it
UnityEngine.GUIUtility: ProcessEvent (int,intptr,bool&)

Error building Player: Error removing component when merging Prefab changes: Can't remove Camera because HDAdditionalCameraData (Script) depends on it

I have to upgrade the unity editor or clear EVERYTHING, both makes my build time Exceed 2 Hours (Compiling shader variants for 2 hours), Before that problem, the first builds took an hour while consecutive builds took less than 1 minute.

What causes these kind of errors? Why does it only happen on the second build?

 

Hey did you ever fix this? my build failign with it too, finding it hard to pin point where the code for it is.

 

I think I changed to IL2CPP and back to Mono.
