I really hope it becomes apparent when you get one. It's strange. The grey space it takes you to specifically is the one you see when you hold the power button where it displays the Restart/Turn off menu, but no menus or information. It may also be the same background used for the permission request screens.
Just wanted to chime in and say I'm having a very similar issue with the Quest 2 and weird model clipping issues outside of the menus, loading through the menus works great - all the environments are rendered fine - but my arms, guns, all enemies, and basically every other "object" does a weird z-fighting clipping thing and makes the objects nearly invisible and the game unplayable. :0 Hope you get your Quest 2 soon!
