Meta VR passthrough underlay not working

I done passthrough according to this tutorial yt - Setting Up Meta XR Passthrough For AR in Unreal Engine
and it worked, i could place 3d objects in my room, but later, when i ran game few hours later it broke by itself and passthrough is over every object and i cant see hands and any 3d actor. what can i do to fix it (i can see them on monitor where passthrough isn’t shown)
