Question The enemy doesn't show movement and isn't attacking and idle when player is close

this is the code, it isnt working

using UnityEngine;
using UnityEngine.AI;

public class EnemyAI : MonoBehaviour
{
public NavMeshAgent agent;
public Transform player;
public LayerMask groundMask, playerLayer;
public Vector3 walkPoint;
bool isWalkPointSet;

public float timeBetweenAttacks;
bool attacked;

public Animator animator;
public LayerMask collisionLayer;

private void Awake()
{
player = GameObject.Find("Player").transform;
agent = GetComponent<NavMeshAgent>();
animator = GetComponent<Animator>();
}

private void Update()
{
inChaseRange = Physics.CheckSphere(transform.position, chaseRange, playerLayer);
inAttackRange = Physics.CheckSphere(transform.position, attackRange, playerLayer);

if (!inAttackRange && !inChaseRange) { Patrol(); Walk(); }
if (!inAttackRange && inChaseRange) { Chase(); Walk(); }
if (inAttackRange && inChaseRange) { Attack(); Idle(); }
}

private void OnTriggerEnter(Collider other)
{
if (collisionLayer == (collisionLayer | (1 << other.gameObject.layer)))
{
GetHit();
}
}

void Patrol()
{
if (!isWalkPointSet) SearchWalkPoint();

if (isWalkPointSet)
agent.SetDestination(walkPoint);

Vector3 distanceToWalkPoint = transform.position - walkPoint;

if (distanceToWalkPoint.magnitude < 1f)
isWalkPointSet = false;
}

private void SearchWalkPoint()
{
float randomZ = Random.Range(-walkPointRange, walkPointRange);
float randomX = Random.Range(-walkPointRange, walkPointRange);

walkPoint = new Vector3(transform.position.x + randomX, transform.position.y, transform.position.z + randomZ);

if (Physics.Raycast(walkPoint, -transform.up, 2f, groundMask))
isWalkPointSet = true;
}

void Chase()
{
agent.SetDestination(player.position);
}

void Attack()
{
agent.SetDestination(transform.position);
transform.LookAt(player);

if (!attacked)
{
animator.SetBool("Attack", true);
attacked = true;
Invoke(nameof(ResetAttack), timeBetweenAttacks);
}
}

void ResetAttack()
{
animator.SetBool("Attack", false);
attacked = false;
}

void Walk()
{
animator.SetFloat("Speed", 1f);
}

void Idle()
{
animator.SetFloat("Speed", 0f);
}

void GetHit()
{

}
}
