SCE_CAMERA_ERROR_NOT_CONNECTED when running on PS4 with disabled Mprpheus

Hi, there,

I am trying to disable the current game with VR support. I have disabled “Start VR” in project setting, and disabled the “Morpheus” plugin. However, when i run the game on PS4, “SCE_CAMERA_ERROR_NOT_CONNECTED” error is shown.
My version of Unreal Engine is v 4.19. I can’t find anywhere in the blueprint having “Enable HMD” at all. Is anyone know what’s going on? And how to stop that camera connection error on PS4?
Thank you very much!
