Answer 1

I ended up rebuilding the application from scratch while omitting my personal XR prefabs and scripts and that fixed it. I don't know exactly what is the issue but I suspect it is my attempt to make the wrap the XRController with a singleton for easier access. Important Tip: When you're making changes and messing with a fragile black box system like XR, be careful and test your app with every iteration.
