I have this code, but it is don`t waiting in WaitForSeconds(), only
Debug.Log(“Starting hit animation”);
otherAnimator.SetBool(“isHitten”, true);
is being completed

using System.Collections;
using UnityEngine;

public class Pikes : MonoBehaviour
{
    public int damage = 1;
    public float speed;
    public GameObject effect;
    GameObject player;
    Animator otherAnimator;

    void Start()
    {
        player = GameObject.FindWithTag("Player");
        otherAnimator = player.GetComponent<Animator>();
    }

    private void Update()
    {
        transform.Translate(Vector3.left * speed);

         if(Input.GetKeyDown(KeyCode.R))
        {

            otherAnimator.SetBool("isHitten", false);
        }
    }

    private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.CompareTag("Player"))
        {
            StartCoroutine(HandleHitAnimation());
            other.GetComponent<Player>().health -= damage;
            Instantiate(effect, transform.position, Quaternion.identity);
            Destroy(gameObject);
        }
    }

    private IEnumerator HandleHitAnimation()
     {
        Debug.Log("Starting hit animation");
        otherAnimator.SetBool("isHitten", true);
        yield return new WaitForSeconds(1);
       Debug.Log("Ending hit animation");
        otherAnimator.SetBool("isHitten", false);
     }
}

Help to fix this and make waitforseconds work.
