C# Unity场景-重新启动按钮导致进程停止

我需要有关重新启动按钮的帮助..当我重新加载场景时，所有进程都将停止。 //开始

void Start()
{
    if (NoAnsweredQuestion == null || NoAnsweredQuestion.Count == 0)
    {
        NoAnsweredQuestion = question.ToList<Question>();
    }

    SetcurrentQuestion();
    StartCoroutine("CountDownTimer");
}

//转换

void SetcurrentQuestion()
{
    int randomQuestionIndex = Random.Range(0, NoAnsweredQuestion.Count);
    currentQuestion = NoAnsweredQuestion[randomQuestionIndex];

    factText.text = currentQuestion.fact;
    correctAnswerText.text = currentQuestion.answered;
}

IEnumerator TransitiontoNextQuestion()
{
    NoAnsweredQuestion.Remove(currentQuestion);

    yield return new WaitForSeconds(delaybetweenquestion);

    SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
}

你重启按钮的信息在哪里？有什么错误？我没有错误，先生。那么你想要什么？你想感谢你创造了这个未知的游戏吗？或者你想发布你的游戏？没有，先生…但我的问题是当我点击按钮重新启动时，重新加载场景将冻结或停止处理整个场景这不是答案。把它编辑成你的问题
