JSON not saving game object list

I was creating my inventory system when I came to save. After I wrote a script for it to save, I've been getting errors and also, when I would look up into a file I could see every value except list: https://gyazo.com/44b5c6d7d080eb2e785ce40f4e6e4094 Here are my codes: using System.Collections.Generic; using UnityEngine; using Newtonsoft.Json; using System.IO;

 public class Savelist : MonoBehaviour
 {
 
     public static void Save(SavingAndLoading.RenameMe renameMe, string path)
     {
         File.WriteAllText(path, JsonConvert.SerializeObject(renameMe, Formatting.Indented));
     }
 
     public static SavingAndLoading.RenameMe Load(string path)
     {
         return JsonConvert.DeserializeObject<SavingAndLoading.RenameMe>(File.ReadAllText(path));
     }
 
 }
 namespace SavingAndLoading
     {
         public class RenameMe
         {
         public float _positionX { get; set; }
         public float _positionY { get; set; }
         public float _positionZ { get; set; }
 
         public float _rotationX { get; set; }
         public float _rotationY { get; set; }
         public float _rotationZ { get; set; }
 
         public int XP { get; set; }
         public int level { get; set; }
         public int MaxHealth { get; set; }
         public List<GameObject> ItemOrbsInInventory { get; set; }
         
             
         }
 }
 

Here I'm calling function

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using System;
 using SavingAndLoading;
 
 public class SaveAndLoad : MonoBehaviour {
     
     public void Save()
     {
         RenameMe saveData = new RenameMe();
 
         saveData.ItemOrbsInInventory = gameObject.GetComponent<Inventory>().ItemOrbsInInventory;
         Savelist.Save(saveData, System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "player.dat");
         print(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "player.dat");
     }
 
     void Load(){
         SavingAndLoading.RenameMe loadData = Savelist.Load(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "player.dat");
 
         gameObject.GetComponent<Inventory>().ItemOrbsInInventory = loadData.ItemOrbsInInventory;
 
     }
     void Start()
     {
         Load();
     }
     
 
     
 }

I think the issue is somewhere with saving. If someone knows how to fix this please answer me.
