Choose beetwen first person and vr pawn in main menu

Hi folks,
im new to unreal and i’m trying create a main menu (see attached

pics) in wich you can choose to load a level in first person character mode (desktop version) or in vr (VR mode)(i’m using the MotionControllerMap from the strater content).
Here’s my problem when i press desktop mode everything works fine but when i hit VR mode i doesnt load my level properly i cant move look around etc.

Do you have any idea how can i switch beetween this two mode ?
