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!
