I just got a kinect the day of the update so can tell if it’s related to this one but your description is close to mine.
Calibration looks OK-ish but I lose the buttons function of one hand!
I see the 2 touch controllers at hand positions and 3 vive controller representing my feet+hip but when i go in VRChat for full body, the hand disappear and replace by a ball.
Can still move it but it’s not recognised as a hand.
