fpscontroller doesnt respawn (maybe transform.position issue?)

Hey guys I´m making a respawn script following a tutorial. Everything works but when I click the "Respawn" button, my fpscontroller doesnt respawn at the spawnpoint but at his last position. https://streamable.com/99264

 public class RespawnSystem : MonoBehaviour
 {
 
     FirstPersonController freezePlayer;
     MeleeSystem freezeAttacking;
     MeshRenderer weapon;
     public Transform respawnLocation;
     public static bool  playerIsDead = false;
     
     
      public Button buttonRespawn;
      public Button buttonMainMenu;
      public Button buttonQuitGame;
 
     void Start()
     {
         freezePlayer = GetComponent(typeof(FirstPersonController)) as FirstPersonController;
         freezeAttacking = GameObject.Find("FirstPersonCharacter").GetComponent(typeof(MeleeSystem)) as MeleeSystem;
         weapon = GameObject.Find("Schwert").GetComponent(typeof(MeshRenderer)) as MeshRenderer;
         
     }
 
     void Update()
     {
         if (playerIsDead == true)
         {
             freezePlayer.enabled = false;
             freezeAttacking.enabled = false;
             weapon.enabled = false;
 
             buttonRespawn.gameObject.SetActive(true);

             Cursor.lockState = CursorLockMode.None;
         }
 
     }
 
      public void RespawnPlayer()
     {
 
         transform.position = respawnLocation.position;
         transform.rotation = respawnLocation.rotation;
 
 
         Debug.Log(transform.position);
 
         gameObject.SendMessage("respawnStats");

         buttonMainMenu.gameObject.SetActive(false);
         buttonQuitGame.gameObject.SetActive(false);
 
 
         Cursor.visible = false;
         Cursor.lockState = CursorLockMode.Locked;
 
         playerIsDead = false;
 
         gameObject.SendMessage("HealthBar");
     }
