Need Help with Save/Load Function

Hey, guys, I'm building Strategy/CityBuilding type of game and I'm trying to implement a saving system but saved items didn't instantiate I can't figure out what's problem I took this code from guide I read and change a little bit for my game but it didn't work here's code.

this is code on gameobject i want to save

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

 
 public class EmptySpaceRegister : MonoBehaviour
 {
     public void Start()
     {
         GlobalControl.SaveEvent += SaveFunction;
     }
     public void OnDestroy()
     {
         GlobalControl.SaveEvent -= SaveFunction;
     }
     public void SaveFunction(object sender, EventArgs args)
     {
         EmptySpaceLocs emptyspace = new EmptySpaceLocs();
         emptyspace.PositionX = transform.position.x;
         emptyspace.PositionY = transform.position.y;
         emptyspace.PositionZ = transform.position.z;
 
         GlobalControl.Instance.GetListForScene().SavedEmptySpaces.Add(emptyspace);
     }
 }
 

this is GlobalController code that controls save system

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using System;
 using System.Runtime.Serialization.Formatters.Binary;
 using System.IO;
 using UnityEngine.SceneManagement;
 
 public class GlobalControl : MonoBehaviour
 {
     public static GlobalControl Instance;
 
     public List<AllBuildingLocs> BuildingList;
 
     public delegate void SaveDelegate(object sender, EventArgs args);
     public static event SaveDelegate SaveEvent;
 
 
     void Awake()
     {
         Application.targetFrameRate = 144;
 
         if (Instance == null)
         {
             DontDestroyOnLoad(gameObject);
             Instance = this;
         }
         else if (Instance != null)
         {
             Destroy(gameObject);
         }
 
     }
     public void InitializeSceneList()
     {
         if(BuildingList == null)
         {
             print("building list is null");
             BuildingList = new List<AllBuildingLocs>();
         }
         bool found = false;
 
         for(int i = 0; i < BuildingList.Count; i++)
         {
             if (BuildingList[i].SceneID == SceneManager.GetActiveScene().buildIndex)
             {
                 found = true;
                 print("Scene was found in saved lists!");
             }
         }
         if (!found)
         {
             AllBuildingLocs newList = new AllBuildingLocs(SceneManager.GetActiveScene().buildIndex);
             BuildingList.Add(newList);
 
             print("Created new list!");
         }
     }
     public AllBuildingLocs GetListForScene()
     {
         for (int i = 0; i < BuildingList.Count; i++)
         {
             if (BuildingList[i].SceneID == SceneManager.GetActiveScene().buildIndex)
                 return BuildingList[i];
         }
 
         print("Total list count: " + BuildingList.Count.ToString() + " , not found index: " + SceneManager.GetActiveScene().buildIndex.ToString());
         return null;
     }
 
     public CurrencyData LocalCopyOfCurrency;
     public bool IsSceneBeingLoaded = false;
     public bool IsSceneBeingTransitioned = false;
 
     public CurrencyManager currency;
     
     public void CurrencyColb()
     {
         LocalCopyOfCurrency.Gold = currency.GoldData;
         LocalCopyOfCurrency.Food = currency.FoodData;
         LocalCopyOfCurrency.Wood = currency.WoodData;
         LocalCopyOfCurrency.Stone = currency.StoneData;
     }
 
     public void FireSaveEvent()
     {
 
         GetListForScene().SavedEmptySpaces = new List<EmptySpaceLocs>();
        
         if (SaveEvent != null)
             SaveEvent(null, null);
     }
 
     public void SaveData()
     {
         if (!Directory.Exists("Saves"))
             Directory.CreateDirectory("Saves");
 
         FireSaveEvent();
 
         BinaryFormatter formatter = new BinaryFormatter();
         FileStream saveFile = File.Create("Saves/save.binary");
         FileStream SaveObjects = File.Create("saves/saveObjects.binary");
 
         CurrencyColb();
 
 
         formatter.Serialize(saveFile, LocalCopyOfCurrency);
         formatter.Serialize(SaveObjects, BuildingList);
 
         saveFile.Close();
         SaveObjects.Close();
 
         print("Saved!");
     }
     public void LoadData()
     {
         BinaryFormatter formatter = new BinaryFormatter();
         FileStream saveFile = File.Open("Saves/save.binary", FileMode.Open);
         FileStream saveObjects = File.Open("Saves/saveObjects.binary", FileMode.Open);
         
 
         LocalCopyOfCurrency = (CurrencyData)formatter.Deserialize(saveFile);
         BuildingList = (List<AllBuildingLocs>)formatter.Deserialize(saveObjects);
 
         saveFile.Close();
         saveObjects.Close();
 
         currency.GoldData = LocalCopyOfCurrency.Gold;
         currency.FoodData = LocalCopyOfCurrency.Food;
         currency.WoodData = LocalCopyOfCurrency.Wood;
         currency.StoneData = LocalCopyOfCurrency.Stone;
 
         print("Loaded");
     }
     public void SaveButton()
     {
         SaveData();
     }
     public void LoadButton()
     {
         LoadData();
     }
 }
 

and this is spawner code

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class MapManager : MonoBehaviour
 {
     public GameObject EmptySpacePrefab;
 
     void Start()
     {
         GlobalControl.Instance.InitializeSceneList();
 
         if (GlobalControl.Instance.IsSceneBeingLoaded || GlobalControl.Instance.IsSceneBeingTransitioned)
         {
             AllBuildingLocs localList = GlobalControl.Instance.GetListForScene();
 
             if (localList != null)
             {
                 print("Saved potions count: " + localList.SavedEmptySpaces.Count);
 
                 for (int i = 0; i < localList.SavedEmptySpaces.Count; i++)
                 {
                     GameObject EmptySpace = (GameObject)Instantiate(EmptySpacePrefab);
                     EmptySpace.transform.position = new Vector3(localList.SavedEmptySpaces[i].PositionX,
                                                                     localList.SavedEmptySpaces[i].PositionY,
                                                                     localList.SavedEmptySpaces[i].PositionZ);
                 }
 
             }
             else
                 print("Local List was null!");
         }
     }
 }
 

in case if you guys ask this is savedata code im using

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 [System.Serializable]
 public class CurrencyData
 {
     public float Gold;
     public float Food;
     public float Wood;
     public float Stone;
 }
 
 [System.Serializable]
 public class EmptySpaceLocs
 {
     public float PositionX, PositionY, PositionZ;
 }
 
 
 [System.Serializable]
 public class AllBuildingLocs
 {
     public int SceneID;
     public List<EmptySpaceLocs> SavedEmptySpaces;
 
     public AllBuildingLocs(int newSceneID)
     {
         this.SceneID = newSceneID;
         this.SavedEmptySpaces = new List<EmptySpaceLocs>();
     }
 }
