When I want to kill an enemy with a strong attack, the enemy just gets stuck. How do I fix this?

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

public class attack : MonoBehaviour { public Animator attackAnim; public Transform attackPoint; public float attackRange; public LayerMask enemyLayers;

 public int normalDamage;
 public int heavyDamage;
 public float attackRate =2f;
 float nextAttackTime;


 // Start is called before the first frame update
 void Start()
 {
 }

 // Update is called once per frame
 void Update()
 {

     GameObject theDagger = GameObject.Find("Dagger");
     pickup pdagger = theDagger.GetComponent<pickup>();

     GameObject theMace = GameObject.Find("Mace");
     macepickup pmace = theMace.GetComponent<macepickup>();

     GameObject theSword = GameObject.Find("Sword");
     swordpickup psword = theSword.GetComponent<swordpickup>();
     if(pdagger.daggerEquipped == true)
     {
         attackPoint = theDagger.transform.Find("ATTACKPOINT1");
         normalDamage = 20;
         heavyDamage = 30;
     }
     if(pmace.maceEquipped == true)
     {
         attackPoint = theMace.transform.Find("ATTACKPOINT2");
         normalDamage = 45;
         heavyDamage = 55;
     }
     if(psword.swordEquipped == true)
     {
         attackPoint = theSword.transform.Find("ATTACKPOINT3");
         normalDamage = 15;
         heavyDamage = 27;

     }


     if(Time.time >= nextAttackTime)
     {
         //normal attack
         if(Input.GetKeyDown(KeyCode.Mouse0))
         {
             attackAnim.SetTrigger("isAttacking");
             Collider[] hitEnemies = Physics.OverlapSphere(attackPoint.position, attackRange, enemyLayers);
             foreach(Collider enemy in hitEnemies)
             {
                 enemy.GetComponent<normalEnemy>().TakeDamage(normalDamage);
             }
             nextAttackTime = Time.time + 1f/attackRate;
             
         }
         

         //strong attack
         if(Input.GetKeyDown(KeyCode.Mouse1))
         {
             attackAnim.SetTrigger("isStrongAttacking");
             Collider[] strongHit = Physics.OverlapSphere(attackPoint.position, attackRange, enemyLayers);
             foreach(Collider strongHitThis in strongHit)
             {
                 strongHitThis.GetComponent<normalEnemy>().TakeHeavyDamage(heavyDamage);
             }
             nextAttackTime = Time.time + 1f/attackRate;
         }
     }
 }

 void OnDrawGizmosSelected()
 {
     if(attackPoint == null)
     return;

     Gizmos.color = new Color(1,1,0,0.75f);
     Gizmos.DrawSphere(attackPoint.position, attackRange);
 }

}

public class normalEnemy : MonoBehaviour { public Animator animator; bool normalhit;

 public int maxHealth = 100;

 // Start is called before the first frame update

     currentHealth -= normalDamage;

         Die();
