Rarely character can't move

testers of my game have been reporting this bug TONS of time, but I never got it, but finally this bug happened to me. For some reason, my character can’t move at all
(this bug only happens ingame thats why im using dex)

btw the humanoid WalkToPoint property works, but normal moving doesn’t, also walkspeed isn’t set to 0

try setting any extra parts to no mass
