Player respawn not working like intended

My "PlayerDeath" animation has a AnimationEvent that starts PlayerDeath(), all works fine, but the animation plays twice for some reason. So two deathGraves get created and the character health is 1/4 of its max value and not 1/2. I am new to programming, so maybe I missed something. Help would be very appreciated.

 public class CharacterCombat : MonoBehaviour
 {
     public int maxHealthPlayer = 200;
     public int currentHealthPlayer;
 public HealthBar2 healthBar2;
 public Animator animator;
 public GameObject deathGrave;
 public Transform characterObject;
 int notHealthy;
 
     void Start()
     {
         currentHealthPlayer = maxHealthPlayer;
         healthBar2.SetMaxHealth(currentHealthPlayer);
         notHealthy = maxHealthPlayer/2;
     }
 
     void Update()
     {
         if (currentHealthPlayer <= 0)
         {
             DeathAnimation();
             Debug.Log("CharacterDeath");
         }
     }
 
     public void TakeDamageP(int damageP)
     {
         currentHealthPlayer -= damageP;
         healthBar2.SetHealth(currentHealthPlayer);
         animator.SetTrigger("GotHit");
     }
 
     public void PlayerDeath()
     {
         Instantiate(deathGrave, characterObject.position, characterObject.rotation);
         currentHealthPlayer = notHealthy;
         notHealthy = currentHealthPlayer/2;
         healthBar2.SetHealth(currentHealthPlayer);
     }
 
     void OnCollisionEnter2D(Collision2D collision)
     {
         if (collision.gameObject.tag == "WorldTrap")
         {
             TakeDamageP(20);
         }
     }
 
     void DeathAnimation()
     {
         animator.SetTrigger("PlayerDeath");
     }
 }
