Question about different on running method in [ContextMenu("xxx")] and onClick() in UI Button

Hi guys, i've experienced some weired issue for my SAVELOAD. When i use [ContextMenu("xxx")] to run my method i can immediatetly go to the position i stored. But when i use onClick() in UI Button to call my method i cant move my player's position (I'm using this video to create my saveLoad https://www.youtube.com/watch?v=f5GvfZfy3yk&t=708s)

this is how i restore my data`using System.Collections; using System.Collections.Generic; using UnityEngine; using System; using UnityEngine.UI;

namespace Assets.GameSystem.SaveSystem3 { public class LevelSystem : MonoBehaviour, ISaveable { public GameObject player; public GameObject text1; public GameObject timerText; public TimerController timerController; public TriggerArea triggerArea1; public TriggerArea triggerArea2; public TriggerArea triggerArea3; [SerializeField] private string level = "Menu"; [SerializeField] public float pX; [SerializeField] public float pY; [SerializeField] public float pZ; [SerializeField] public float rX; [SerializeField] public float rY; [SerializeField] public float rZ; [SerializeField] private string achievment; [SerializeField] private bool achieve11 = false; [SerializeField] private bool achieve22 = false; [SerializeField] private bool achieve33 = false; [SerializeField] private string timer; [SerializeField] private float s; [SerializeField] private int m; [SerializeField] private int h;

     public object CaptureState()
     {
         return new SaveData
         {
             level = level,
             pX = player.transform.position.x,
             pY = player.transform.position.y,
             pZ = player.transform.position.z,
             rX = player.transform.rotation.x,
             rY = player.transform.rotation.y,
             rZ = player.transform.rotation.z,
             achievment = text1.GetComponent<Text>().text,
             achieve11 = triggerArea1.achive1,
             achieve22 = triggerArea2.achive2,
             achieve33 = triggerArea3.achive3,
             s = timerController.secondsCount,
             m = timerController.minuteCount,
             h = timerController.hourCount
         };
     }

     public void RestoreState(object state)
     {
         var saveData = (SaveData)state;

         level = saveData.level;
         pX = saveData.pX;
         pY = saveData.pY;
         pZ = saveData.pZ;
         rX = saveData.rX;
         rY = saveData.rY;
         rZ = saveData.rZ;

         player.transform.position = new Vector3(pX, pY, pZ);
         player.transform.eulerAngles = new Vector3(rX, rY, rZ);

         //player.transform.position = playerPosition;
         //player.transform.eulerAngles = playerRotation;

         achievment = saveData.achievment;
         text1.GetComponent<Text>().text = achievment;

         achieve11 = saveData.achieve11;
         triggerArea1.achive1 = achieve11;
         achieve22 = saveData.achieve22;
         triggerArea2.achive2 = achieve22;
         achieve33 = saveData.achieve33;
         triggerArea3.achive3 = achieve33;

         s = saveData.s;
         timerController.secondsCount = s;
         m = saveData.m;
         timerController.minuteCount = m;
         h = saveData.h;
         timerController.hourCount = h;

     }

     [Serializable]
     private struct SaveData
     {
         public string level;
         public float pX;
         public float pY;
         public float pZ;
