PlayerPrefs not saving after i quiet application

Hi! so i have a playerpreffs thats not saving after i quiet the application and one that does, the code of them look the same (to me), and wondering why its not saving

{

 private GameObject StartPos;
 private GameObject PlayerPos;

 public Text scoreText;
 public Text hiScoreText;

 public static float scoreCount;
 public static float hiScoreCount;
 private float yDistance;

 public static float statScore;
 public static bool justDied = false;
 public static float NewStatScore;
 

 public float pointsPerSecond;

 public bool scoreIncreasing;



 private void Start()
 {
     StartPos = GameObject.FindGameObjectWithTag("StartPos");
     PlayerPos = GameObject.FindGameObjectWithTag("Player");

     if (PlayerPrefs.HasKey("HighScore"))
     {
         hiScoreCount = PlayerPrefs.GetFloat("HighScore");
     }

     if (PlayerPrefs.HasKey("TotalHeight"))
     {
         NewStatScore = PlayerPrefs.GetFloat("TotalHeight");
     }
 }

 
 private void Update()
 {
     if (scoreIncreasing && playerController.dead == false)
     {
         // points per second
         yDistance = PlayerPos.transform.position.y - StartPos.transform.position.y;
         scoreCount = pointsPerSecond * yDistance;
     }
     
     if (scoreCount > hiScoreCount)
     {
         hiScoreCount = scoreCount;
         PlayerPrefs.SetFloat("HighScore", hiScoreCount);
         
     }
     // print out on screen
     scoreText.text = "Score: " + Mathf.Round(scoreCount) + "m";
     hiScoreText.text = "High Score: " + Mathf.Round(hiScoreCount) + "m";

     if (justDied == true)
     {
         NewStatScore = NewStatScore + scoreCount;
         PlayerPrefs.SetFloat("TotalHeight", NewStatScore);
         justDied = false;
     }

 }

}

here i have 2 player preffs. one thats TotalHeight and one thats Highscore. The highscore one is saving while the TotalHeight isnt. any tips?
