I believe the error is that a static variable instance is not set to anything. In any GamePlayController component, in Awake method, call instance = this

i Did It public static GamePlayController instance;

 [SerializeField]

 public Text scoretext, cointext, lifetext, gameOverScoreText, gameOverCoinText;

 [SerializeField]
 public GameObject pausePanel, gameOverPanel;

 [SerializeField]
 public GameObject ReadyButton;



 // Use this for initialization
 void awake() {
 
     $$anonymous$$akeInstance ();

 }

 void start(){
     Time.timeScale =0f;
 }
 
 // Update is called once per frame
 void $$anonymous$$akeInstance () {
 
     if (instance = null) {

         instance = this;
     }
 }

 public void GameOverShowPanel (int finalScore, int finalCoinScore){
     


     gameOverPanel.SetActive (true);
     gameOverScoreText.text = finalScore.ToString ();
     gameOverCoinText.text = finalCoinScore.ToString ();
     StartCoroutine(GameOverLoad$$anonymous$$ain$$anonymous$$enu());
         }

         IEnumerator GameOverLoad$$anonymous$$ain$$anonymous$$enu(){
             yield return  new WaitForSeconds(3.0f);
             Scene$$anonymous$$anager.LoadScene("$$anonymous$$ain$$anonymous$$enuScene");
         }

 public void PlayerDiedRestartTheGame(){
     StartCoroutine (PlayerDiedRestart ());
 }

 IEnumerator PlayerDiedRestart(){
     yield return new WaitForSeconds (1f);
     Scene$$anonymous$$anager.LoadScene ("Gameplay");
 }

 public void SetScore(int Score){
     scoretext.text = "x" + Score;
 }
 public void SetCoinScore(int CoinScore){
     cointext.text= "x" + CoinScore;
 }
 public void SetLifeScore(int LifeScore){
     lifetext.text =  "x" + LifeScore;
 }

 public void PauseTheGame(){

     Time.timeScale = 0f;
     pausePanel.SetActive (true);
 }

 public void ResumeGame(){
     Time.timeScale = 1f;
     pausePanel.SetActive (false);
 }
 public void QuitGame(){
     Time.timeScale = 1f;
     Scene$$anonymous$$anager.LoadScene ("$$anonymous$$ain$$anonymous$$enuScene");
 }
 public void StartTheGame(){
     Time.timeScale = 1f;
     ReadyButton.SetActive (false);
 }


 }

It has to be Awake, not awake. Everything is case sEnsItiVe.
