I have the exact same problem. I’m using my smartphone with VRidge, Kinekt 360, and the wii controllers.
When I’m trying to have full track from kinekt (head, hands and body), it sais “Failed to load input bindings for VRchat, please select another binding options”.
The character appears with the T-bone position, and I see 3 white balls around (wraist and the 2 legs), and I’m unable to do anything.
However, if I disable only the body tracking, everything works perfect and i don’t have any problem with bindings
