Can't teleport to checkpoint/bench in other scene upon death. please help me.

hello there! ive got a problem with a hollow knight-like bench system. upon dying, i want the player to respawn in another scene at a certain point.

which is an object with a set position thisPosition to which this script is attached:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.SceneManagement;
 public class Bench_Home : MonoBehaviour {
     
     private CharacterController2D controller;
     public GameManagerScript gm;
     static string Load_Home = "Home";
     private GameObject player;
     public Vector2 thisPosition;
 
     void Start() {
         //WICHTIG!!! reference so machen, um auch bei scene change die reference zum script zu behalten   
         if (gm == null) {
             gm = GameObject.FindGameObjectWithTag("Player").gameObject.GetComponent<GameManagerScript>();
         }
         if (controller == null) { 
             controller = GameObject.FindGameObjectWithTag("Player").GetComponent<CharacterController2D>(); 
         }
         if (player == null) {
             player = GameObject.FindGameObjectWithTag("Player");
         }
     }
 
     void OnTriggerEnter2D(Collider2D other) {
         if (other.CompareTag("Player")) {
             gm.lastBenchPos = thisPosition;
         }
     }
 
     void Update() {      
         thisPosition = new Vector2(-64.01f, -16.01f);
         //check for last bench position
             if (controller.respawned && thisPosition == gm.lastBenchPos) {
                 LoadScene(Load_Home);
                 Physics2D.IgnoreLayerCollision(7, 8, false);
                 Physics2D.IgnoreLayerCollision(7, 9, false);
                 player.transform.position = thisPosition;
                 //check for child object and enable
                 controller.rb.gravityScale = 3;
                                 
             }
             controller.respawned = false;
     }
 
 
     public static void LoadScene(string SceneNameToLoad) {
         PendingPreviousScene = SceneManager.GetActiveScene().name;
         SceneManager.sceneLoaded += ActivatorAndUnloader;
         SceneManager.LoadScene(SceneNameToLoad, LoadSceneMode.Additive);
         Debug.Log("Home was loaded");
     }
 
     static string PendingPreviousScene;
     static void ActivatorAndUnloader(Scene scene, LoadSceneMode mode) {
         SceneManager.sceneLoaded -= ActivatorAndUnloader;
         SceneManager.SetActiveScene(scene);
         SceneManager.UnloadSceneAsync(PendingPreviousScene);
     }
 
 
 }
 

when i instantiate my player, i am spawned at the location of gm.lastBenchPos and upon interaction with another "bench", i want gm.lastBenchPos to update.

in the inspector nothing happens, but if i put a Debug.Log(lastBenchPos) into Update() of GameManagerScript, the values are changing.

GameManagerScript is attached to the Player(Clone) created from prefab.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class GameManagerScript : MonoBehaviour
 {
     public Vector2 lastCheckPointPos;
     public Vector2 lastBenchPos;
 }
 

i need the values to be able to fullfil the if-statement of the other bench, which has different coordinates.

and make it able for the player to teleport there upon death.

im trying to make this work since 3 full days and im slowly descending into madness because i need to have this figured out. please help me.

thanks in advance!
