    I found a fix. Change below lines in OVRSkeleton.cs,
    if (capsuleGO.activeSelf)
    {
        capsule.CapsuleRigidbody.MovePosition(bone.position);
        capsule.CapsuleRigidbody.MovePosition(bone.rotation);
    }
    else
    {
        capsuleGO.SetActive(true);
        capsule.CapsuleRigidbody.position = bone.position;
        capsule.CapsuleRigidbody.rotation = bone.rotation;
    }
    to this:
    if (capsuleGO.activeSelf)
    {
        capsule.CapsuleRigidbody.gameObject.transform.position = bone.position;
        capsule.CapsuleRigidbody.gameObject.transform.rotation = bone.rotation;
    }
    else
    {
        capsuleGO.SetActive(true);
        capsule.CapsuleRigidbody.gameObject.transform.position = bone.position;
        capsule.CapsuleRigidbody.gameObject.transform.rotation = bone.rotation;
    }
    Looks like assigning position and rotation to the rigid body doesn’t work at all.
    Since the OVRSkeleton is the part of sdk, it will be better if Oculus fixes it in its Oculus Integration package.

I have a better solution, please feel free to try it

if (capsuleGO.activeSelf)
{
    capsuleGO.SetActive(false);         //Raymond Tsang debug @ 2020-02-14
    capsuleGO.SetActive(true);          //Raymond Tsang debug @ 2020-02-14
    capsule.CapsuleRigidbody.MovePosition(bone.position);
    capsule.CapsuleRigidbody.MovePosition(bone.rotation);
}
else
{
    capsuleGO.SetActive(true);
    capsule.CapsuleRigidbody.gameObject.transform.position = bone.position;
    capsule.CapsuleRigidbody.gameObject.transform.rotation = bone.rotation;
}
