Static Gameobjects Destroy on Reload

Hi a recursiv Ask for you :

I want Dont destroy Gameobjects after Reload Scene.

1. Game Object CFunc ist not createt in Scene

COde OF CFUNC

 public  class CFunctions : Singleton<CFunctions>
 {
     static GameObject ScoreManager = GameObject.Find("ScoreManager");
     static GameObject PreviewPic = GameObject.Find("PreviewPic");
     static GameObjectPreviewTextUpImg = GameObject.Find("PreviewTextUpImg");
 
 // AND TOO MUCH MORE
 }

Code of SIngleton

 public abstract class Singleton<T> : MonoBehaviour where T : MonoBehaviour
 {
     private static T instance;
     public static T Instance
     {
         get
         {
             if (instance == null)  instance = FindObjectOfType<T>();
 
             return instance;
         }
     }
 }

RELOAD SCENE LOOK THIS

     public  void restartmatch()
     {
         int scene = SceneManager.GetActiveScene().buildIndex;
         SceneManager.LoadScene(scene, LoadSceneMode.Single);
     }


 

SO i thought with a on Awake functions use

 DontDestroyOnLoad(gameObject)

I think its saved the Cfunc singleton but the inside static Methods dont save . I get continuly The Gameobject has been destroyed error, on line where i use the first Gobj
