The player rotates by the initial degree when the joystick is released. How to fix?

Question

C++ / C#

Made controls using the Joystick Pack asset. The video shows that when you release the joystick, the character turns sharply.

private void FixedUpdate()
    {
            MoveAndroid();
            LookAtAndroid();
    }

    private void MoveAndroid()
    {
        MoveVelosity = new Vector2(joystick_Move.Horizontal, joystick_Move.Vertical).normalized * Speed;
        Body.velocity = MoveVelosity * Time.fixedDeltaTime;
        LookAtAndroid();
    }
    public void LookAtAndroid()
    {

        float Angle = Mathf.Atan2(joystick_Move.Vertical, joystick_Move.Horizontal) * Mathf.Rad2Deg;
        Quaternion OldRotation = transform.rotation;
        transform.eulerAngles = new Vector3(0, 0, Angle);


        if (Joystick_Attack.transform.Find("Handle").localPosition != new Vector3(0, 0, 0))
        {
            Angle = Mathf.Atan2(Joystick_Attack.Vertical, Joystick_Attack.Horizontal) * Mathf.Rad2Deg;
            Joystick_Attack.
            transform.eulerAngles = new Vector3(0, 0, Angle);
        }
        
    }
