Physics Constraint Chain Pulls Apart When Grabbing Root in VR (UE5)

I’m building a modular puppet using physics constraints in UE5. Each limb is a separate mesh (upper arm, lower arm, hand) attached via Physics Constraints. When I grab the hand, everything works. But when I grab the body, the arm pulls apart slightly, like it’s not tightly connected to the body. I’ve tried angular motors, soft limits, SLERP, projection, and adjusting stiffness/damping. Using UE5.4 and the VR template.
