Unity refuses to let me add an EventSystem to my hierarchy.

I’ve tried adding the Event System as a standalone object, as a component of a separate UI object, etc. When I hit add, it does not show up in the Hierarchy, and instead a deselected, empty version shows up in the Inspector (but does not actually exist in the hierarchy or the game). Has anyone else had this bug? Am I doing something wrong, or is this just an issue on Unity’s end?

I have Unity Version 2018.3.8f1

EDIT: I literally had to export an EventSystem from an older project to my game to get it in the hierarchy. I’m almost positive this is a bug.

Had to reinstall the same version again, then it allowed me to add EventSystem.

Had same issue with 2018.3.13f1,
seems to happen if you do this:

  • Import Oculus VR SDK into project
  • (here you can still add event system)
  • Run one of the Oculus VR scenes
  • Now you cannot add event system anymore
  • Restarting Unity helps (but still cannot add it into scenes with oculus VR stuff)

(can also copy eventsystem from Assets/Oculus/VR/Scenes/UI.Unity, although it has some oculus UI override thing)
