My void Start won't work

Hello everyone. I'm basically a noob on unity, so i need your help on this one. I'm modifying a code i scrape from a codemonkey tutorial. They idea is to save a value at the end of each game, and compare this value to the previous in order for the player to understand is improvement compared to his previous play. My problem is that my second void sart (in the Highscores Private class) won't start when i launch the game. If everyone have an explanation i will gladly hear it. Thanks a lot, the code is below. using System.Collections; using System.Collections.Generic; using UnityEngine; using CodeMonkey; using CodeMonkey.Utils; using System.IO;

[System.Serializable] public class GameHandler : MonoBehaviour {

 private Transform entryContainer;
 private Transform entryTemplate;
 private int MaxObjCount = 2;
 private List<Transform> highscoreEntryTransformList;


 private void Awake()
 {
     
  

     

     string jsonString = PlayerPrefs.GetString("highscoreTable");
     Highscores highscores = JsonUtility.FromJson<Highscores>(jsonString);
     
     if (highscores == null)
     {
         // There's no stored table, initialize
         Debug.Log("Initializing table with default values...");
         AddHighscoreEntry(0);
         AddHighscoreEntry(0);
      
         // Reload
         jsonString = PlayerPrefs.GetString("highscoreTable");
         highscores = JsonUtility.FromJson<Highscores>(jsonString);
     }

    

     highscoreEntryTransformList = new List<Transform>();
   

 }

 


 public static void AddHighscoreEntry(float score)
 {
     



     // Create HighscoreEntry
  // PlayerPrefs.DeleteAll();
     HighscoreEntry highscoreEntry = new HighscoreEntry { score = score};
     

     // Load saved Highscores
     string jsonString = PlayerPrefs.GetString("highscoreTable");
     Highscores highscores = JsonUtility.FromJson<Highscores>(jsonString);

     if (highscores == null)
     {
         // There's no stored table, initialize
         highscores = new Highscores()
         {
             highscoreEntryList = new List<HighscoreEntry>()
         };
     }
     
     // Add new entry to Highscores
     highscores.highscoreEntryList.Add(highscoreEntry);

     /*  while (highscoreEntryTransformList.Count >MaxObjCount)
       {
           if (highscoreEntryTransformList[0] != null)
               Destroy(highscoreEntryTransformList[0].highscores);
           highscoreEntryTransformList.RemoveAt(0);
       }*/

     // Remove Old entry to Highscores

     // Save updated Highscores
 
     string json = JsonUtility.ToJson(highscores);
     PlayerPrefs.SetString("highscoreTable", json);
     PlayerPrefs.Save();
    // Debug.Log(PlayerPrefs.GetString("highscoreTable"));
