I can confirm that it works again, after unistalling vbs on my computer and re-installing again. I've noticed that there was an streaming app update on the focus itself too. To be honest i was testing out quite a lot different system options and since I'm still new to this whole vbs-steamvr-unreal integration I can't spot out what the issue was exactly. But what i've noticed is that inside steamvr, the system is recognizing your bare-hands as controllers which is maybe a good indicator that steam is getting the hand-tracking right.
