How to look left and right with a 2 player controller when up and down is working

I have attempted to create 2 person local game but can only get both players to look up and down, but not left and right. It attempts left and right but to no avail. The first script with the movement and controller are as follows. This is then fed into a second script that is replicated with the unity input system which is the 2nd one

 private float mouseSensitivity = 100f;
 private float xRotation = 0f;
 private Transform playerBody;
 private Vector2 mouseLook;

 [SerializeField]
 private int playerIndex = 0;
 private CharacterController controller;//reference to player controller

 //move
 private float moveSpeed = 3f;
 private Vector3 moveDirection = Vector3.zero;//Vector3(0, 0, 0)passing through 3 axis
 private Vector2 inputVector = Vector2.zero;//Vector2(0, 0, 0)passing through 2 axis - input vectr for movement

 

 private void Awake()
 {
     playerBody = transform.GetChild(1);
     Cursor.lockState = CursorLockMode.Locked;


     controller = GetComponent<CharacterController>();//component for player controller
 }
 
 public void SetInputVector(Vector2 direction)//public method to set direction where we want to move
 {
     inputVector = direction;//inputvector at //Vector3(0, 0, 0) = direction
 }
 
 public void SetInputVectorLook(Vector2 looking)//public method to set direction where we want to move
 {
     xRotation = looking;//inputvector at //Vector3(0, 0, 0) = direction
 }


 public int GetPlayerIndex()
 {
     return playerIndex;
 }


 // Update is called once per frame
 void Update()
 {
     //calculation for movement
     moveDirection = new Vector3(inputVector.x, 0, inputVector.y);
     moveDirection = transform.TransformDirection(moveDirection);
     moveDirection *= moveSpeed;
     controller.Move(moveDirection * Time.deltaTime);//executive movement


     float mouseX = mouseLook.x * mouseSensitivity * Time.deltaTime;
     float mouseY = mouseLook.y * mouseSensitivity * Time.deltaTime;
     xRotation -= mouseY;
     xRotation = Mathf.Clamp(xRotation, -90f, 90);
     playerBody.transform.localRotation = Quaternion.Euler(xRotation, 0, 0);
     playerBody.Rotate(Vector3.up * mouseX);//execute rotation

 }

{}

 private PlayerInput playerInput;
 private Mover mover;


 private void Awake()
 {
     playerInput = GetComponent<PlayerInput>();
     var movers = FindObjectsOfType<Mover>();
     var index = playerInput.playerIndex;
     mover = movers.FirstOrDefault(m => m.GetPlayerIndex() == index);//get mover object for player number
 }
 // Start is called before the first frame update
 void Start()
 {
     
 }

 // Update is called once per frame
 public void OnMove(CallbackContext context)//a method to player input, 
 {
     mover.SetInputVector(context.ReadValue<Vector2>());//set input vector on mover i.e. //read value form mover script
 }
 public void OnLook(CallbackContext context)//a method to player input, 
 {
     mover.SetInputVectorLook(context.ReadValue<Vector2>());//set input vector on mover i.e. //read value form mover script
 }
