Camera changing Scene

Hi Guys i have one scene with a camera an special script. Also i have a GameManager class with this code to dont destroy it (the game manager and the childs objects)

  private IStateBase activeState;
     private static StateManager instanceRef;
 
     private Main mainScript;
 
     void Awake() {
 
         if (instanceRef == null) {
             instanceRef = this;
             DontDestroyOnLoad(gameObject);
             Debug.Log("Object DONT detroyed! ->" + gameObject.name);
         }
         else{
             DestroyImmediate(gameObject);
             Debug.Log("Object  Detroyed!!! -> " + gameObject.name);
         }
 
     } // Awake

everything goes smooth....But, the camera is stick no get any input. I check it and it has the script attached and all the features as it has to be.... anyway i can´t move. The camera is a child of the gameobject with has the awake method... if i remove the awake method the camera works... so i don´t have a clue what it is happend any clue guys?
