Why is my value of a variable playerpref always the same?

I have no expirience with scripting and started a few weeks ago with Unity and some tutorials.
But now something doesnt work, so in my game, when you collide with a coin you get some score.
This is managed by the ScoreManager Script. I made a Playerpref of the ScoreValue and loaded it in the second script in the game over scene. But the value is everytime 11. I cant find the fault. Thank you in advance.

This is the ScoreManager script:

      using System.Collections;
      using System.Collections.Generic;
      using UnityEngine;
      using TMPro;
      using UnityEngine.SceneManagement;

      public class ScoreManager : MonoBehaviour
       {
      public static ScoreManager instance;
      public TextMeshProUGUI text;

public int score;

// Start is called before the first frame update
void Start()
{
    if(instance == null)
    {
        instance = this;
    }  

}
    public void ChangeScore(int coinValue)
{
    score += coinValue;
    text.text = "Score :" + score.ToString();

    
}

public void SaveData()
{
    PlayerPrefs.SetInt("ScoreText", score);
    PlayerPrefs.Save (); 
}
}

and this is the Loadscript in the GameOver scene:

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

    public class LoadData : MonoBehaviour
    {
private int score;
public TextMeshProUGUI text;

// Start is called before the first frame update
void Update()
{
    score = PlayerPrefs.GetInt("ScoreText");

    text.text = "Score :" + score.ToString();
}

}

I fixed it, the problem was that I saved the Playerprefs not in Update method.
