I'm using Pimax headset plus Index controllers

Since about a week ago Steam VR / Vrchat got updates. Since then I constantly have forced gestures in VRC. I have no proper fingertracking in the game and my avatar constantly has either this or that gesture and face expression active. The specific gesture / face expression I have roughly corresponds with position of my IRL hands/fingers. My avatar's hands and face expression are always in non-default state. There is no way for the avatar to have "no hand gesture" and normal / default face expression.

If needed, I can provide video of what's going on with these forced gestures.
