Animator pushes my mesh 100 meters away, on iOS build only

My scene is working perfectly as expected when testing on the editor on mac.

However when I try to build the game for iOS, my mesh disappears. Please see attached photos.

• I can still se their blob shadow on the phone, but the mesh is not there.

• I added some logging, the mesh is pushed randomly 100 meters along Y axis. The parent game object still ok.

• When I remove the animator component, it fixes the problem.

• Only happens on iOS

Im stuck with this for a few days without a solution, any help appreciated, thanks guy.

It looks OK on PC/MAC:

on iOS, the mesh randomly moved away, about 100 meters vertically on Y-Axis. It seems to happen when the character moves.
