VRPawn stuck at floor in Built project PC/VR - Quest 2.

I’m interested in using the latest version of Epic and untied from Meta; hence using the Meta XR plugin. I don’t just develop for Meta.

Doesn’t even work properly with Epic’s basic VR template?
On both Android and Windows the bottom three fingers of the hands do not animate when pressing the Grip button until you use the hand menus; also, only in Windows, the projectile doesn’t come out every time you shoot.

Have you tried to reproduce the bug?
