Why does my characters child object jitter with pixel perfect camera component?

My character and everyt$$anonymous$$ng else works just fine with no jitter using the pixel perfect camera component. However, the gun, w$$anonymous$$ch is a child of the character is jittering and lagging be$$anonymous$$nd. the jittering seems to be worsened yet by enabling my look at cursor script (listed below)

Details: Unity 2021.3.13f1 URP

2d Pixel Perfect 5.0.1

look at cursor script:

 void LateUpdate()
 {

     Vector3 _mousePos = Input.mousePosition;
     _mousePos.z = 0;

     Vector3 _lookAtPos = Camera.main.ScreenToWorldPoint(_mousePos);
     Vector2 _direction = (_lookAtPos - transform.position).normalized;

     transform.right = _direction;

 }

Character Controller script:

 [Header("Attributes")]
 [SerializeField] private float speed;

 private Rigidbody2D playerRb;
 private Vector2 moveInputs;
 private float speedMultiplier = 10f;
 private void Awake()
 {
     playerRb = GetComponent<Rigidbody2D>();
 }
 private void FixedUpdate()
 {
     playerRb.velocity = speed * speedMultiplier * Time.deltaTime * moveInputs.normalized;
 }
 private void Update()
 {
     moveInputs = PlayerInput.GetMoveInput();
 }

Camera follow script:

 [SerializeField] private Transform target;
 [SerializeField] private Vector3 offset;
 private void LateUpdate()
 {
     if(target != null)
         transform.position = target.position + offset;
 }
