fixed update is not being called

Fixed update is not being called! I don’t understand nothing prints at all!

public static Transform CurrentlySelectedObject;
private bool Moving = false;

private void FixedUpdate()
        Debug.Log("Moving   :" + Moving);
        if (Moving == true && CurrentlySelectedObject != null)
            Rigidbody2D Rb = CurrentlySelectedObject.GetComponent<Rigidbody2D>();
            Vector2 direction = (Vector2)CurrentlySelectedObject.position - mousePosition;
            Rb.MovePosition(Rb.position + direction * Time.fixedDeltaTime * 100);

            Debug.Log(Rb.position + " " + direction);

I moved this script to another object. Now this function is called a minimum of zero and a maximum of three times before it stops completely? I thought the issue might have been caused by my fixed time step but that is set to the default 0.02. I have no idea what could be causing this.
