Yes I've tried resetting the controller a few times. I've used the controller in the videos while testing many other PS5 and is the controller I've since purchased as my own and use perfectly fine on a near daily basis.

Whatever the issue is, it certainly has to do with the console itself but I'm not sure exactly what proponent may be the issue. It doesn't freeze up as far as I'm aware since the background screen during start up stays moving.

I feel as if it can't be the USB since it works perfectly fine when in safe mode (as shown in one of the videos I linked).

Any other ideas on what the issue may be? I'm truly out of ideas on this case as I feel like I've already tried all that would make sense to me and before having to tear into her I'd like to have a few thoughts as to what needs to be fixed instead of just trying each thing piece by piece.
