Player Character spinning out of control

Hi folks,
I've got a twin stick project I'm working on. The left joystick (JS) henceforth, moves the player and the right JS controls the player's look direction. The camera hovers above the player in a fixed location. So the look JS should determine exactly where the character looks. When the look JS is released, the character should shoot in that direction.
Currently, the character spins in circle when I push the Look JS and fires all his ammo immediately.
I need help with fixing the spinning ballet

Here is my code

 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 using UnityEngine.AI;
 using Ludiq;
 using Bolt;
 
 
 
 public class PlayerJSControlSc : MonoBehaviour

     public FloatingJoystick moveJS;
     public FloatingJoystick shootJS;
     public float rotationSpeed = 10;
     public int ammo;
     public int mag;
     public Transform shotSpawn;
     public GameObject bullet;
     public float reloadTime;
     public Text ammoCount;
     [HideInInspector]
     int currentMag;
 
    
 
     // Start is called before the first frame update
     void Start()
     {
         stateText.text = "";
         nav = player.GetComponent<NavMeshAgent>();
         animator = player.GetComponent<Animator>();
         moveJS = GameObject.Find("Floating JS_Move").GetComponent<FloatingJoystick>();
         shootJS = GameObject.Find("Floating JS_Shoot").GetComponent<FloatingJoystick>();
     }
 
     // Update is called once per frame
     void Update()
     {
         movePlayer();
         playerShoot();
         ammoCount.text = currentMag+ "/" + ammo;
     }

     {
         //float x = Input.GetAxis("Horizontal");
         //float y = Input.GetAxis("Vertical");
         float x = moveJS.Horizontal;
         float y = moveJS.Vertical;
         nav.velocity = new Vector3(x * moveSpeed, 0, y * moveSpeed);
         if (nav.velocity.x != 0 || nav.velocity.z != 0)
         { animator.SetBool("isRunning", true); }
         else { animator.SetBool("isRunning", false); }

                  player.transform.rotation = Quaternion.RotateTowards(lookRotation, transform.rotation, step);*/
