,Look rotation viewing vector is zero and character always facing 1 direction when idle

,Hi, I'm new to Unity and was wondering if anyone could help me find a fix to a problem where after the character moves, they end up facing generally in the same direction along with an error that states that the Look rotation viewing vector is zero (Line 58 apparently). using System.Collections; using System.Collections.Generic; using UnityEngine;

 public class PlayerController : MonoBehaviour {
 
     public float moveSpeed;
     //public Rigidbody theRB;
     public float jumpForce;
     public CharacterController controller;
 
     private Vector3 moveDirection;
     public float gravityScale;
 
     public Animator anim;
     public Transform pivot;
     public float rotateSpeed;
 
     public GameObject playerModel;
 
     // Use this for initialization
     void Start () {
         //theRB = GetComponent<Rigidbody>();
         controller = GetComponent<CharacterController>();
     }
     
     // Update is called once per frame
     void Update () {
         //theRB.velocity = new Vector3(Input.GetAxis("Horizontal") * moveSpeed, theRB.velocity.y, Input.GetAxis("Vertical") * moveSpeed);
 
         /*if(Input.GetButtonDown("Jump"))
         {
             theRB.velocity = new Vector3(theRB.velocity.x, jumpForce, theRB.velocity.z);
         }*/
 
         //moveDirection = new Vector3(Input.GetAxis("Horizontal") * moveSpeed, moveDirection.y, Input.GetAxis("Vertical") * moveSpeed);
         float yStore = moveDirection.y;
         moveDirection = (transform.forward * Input.GetAxisRaw("Vertical")) + (transform.right * Input.GetAxisRaw("Horizontal"));
         moveDirection = moveDirection.normalized * moveSpeed;
         moveDirection.y = yStore;
 
         if (controller.isGrounded)
         {
             moveDirection.y = 0f;
             if (Input.GetButtonDown("Jump"))
             {
                 moveDirection.y = jumpForce + (Physics.gravity.y * gravityScale * Time.deltaTime);
             }
         }
 
         moveDirection.y = moveDirection.y + (Physics.gravity.y * gravityScale * Time.deltaTime);
         controller.Move(moveDirection * Time.deltaTime);
 
         //Move the player in different directions based on camera look direction
         if (Input.GetAxis("Horizontal") != 0 || Input.GetAxis("Vertical") != 0)
         {
             transform.rotation = Quaternion.Euler(0f, pivot.rotation.eulerAngles.y, 0f);
             Quaternion newRotation = Quaternion.LookRotation(new Vector3(moveDirection.x, 0f, moveDirection.z));
             playerModel.transform.rotation = Quaternion.Slerp(playerModel.transform.rotation, newRotation, rotateSpeed * Time.deltaTime);
         }
 
         anim.SetBool("IsGrounded", controller.isGrounded);
         anim.SetFloat("Speed", (Mathf.Abs(Input.GetAxis("Vertical")) + Mathf.Abs(Input.GetAxis("Horizontal"))));
     }
 }
