ENEMY AI HELP

[warped forum]

I was following this enemy ai video (https://www.youtube.com/watch?v=xppompv1DBg&list=PLPV2KyIb3jR4KLGCCAciWQ5qHudKtYeP7&index=11) and ran into a problem, my enemy walks through walls and does not move if an animation is set. can someone help?

this is the code I am using

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class eye_behavior : MonoBehaviour

{
    public float LookRadius = 10f;
  
    public bool stopright;


    Transform _target;
    NavMeshAgent _agent;
    // Start is called before the first frame update
    void Start()
    {
        _target = PlayerManager.instance.Player.transform;
        _agent = GetComponent<NavMeshAgent>();
    }

    // Update is called once per frame
    void Update()
    {
        float distance = Vector3.Distance(_target.position, transform.position);

        if(distance <= LookRadius)
        {
            //_agent.SetDestination(_target.position);
            GetComponent<Rigidbody>().MovePosition(_target.position);

            if (distance > 0f)
            {
                FaceTarget();
            }
        }
        stopright = Physics.Raycast(transform.position, Vector3.forward, .67f);
        if(stopright)
        {
            
        }
    }

    void FaceTarget ()
    {
        Vector3 direction = (_target.position - transform.position).normalized;
        Quaternion lookRotation = Quaternion.LookRotation(new Vector3(direction.x, direction.y, direction.z));
        //transform.rotation = Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * 5f);
        GetComponent<Rigidbody>().MoveRotation(Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * 5f));
    }
    private void OnDrawGizmosSelected()
    {
        Gizmos.color = Color.red;
        Gizmos.DrawWireSphere(transform.position, LookRadius);
    }
