C#表单在未被告知的情况下消失

因此，我有一个表单，它创建另一个表单并使用

form.ShowDialog（）

调用它，但是在运行过程中的某个时刻，新表单消失了。我可以告诉它仍然在运行，因为我设置了一个计时器，当完成时，会显示一个消息框。消息框在分配的时间之后仍然显示，但表单不再可见

要调用我使用的表单，请使用以下代码：

Player currentUser = new Player(); //Player is a class I've created

private void Game(int PlayerCount)
{
    Current.Hide();
    for (int i = 0; i < PlayerCount; i++)
    {
        currentUser = GloVar.CurrentPlayers[i];
        CashBuilder cb = new CashBuilder(currentUser);
        cb.ShowDialog();
    }
 }

如果答案在正确和不正确之间交替出现，表格似乎（我无法100%澄清）保持可见。 但是，如果我回答正确，那么正确（或不正确和不正确）表格就会消失

我有一个关闭表单的方法，但在计时器启动之前，不会触动它

我已经搜索了大约一个星期来寻找解决方案，尝试了多个线程（让线程工作，但仍然遇到这个问题），我无法思考其他任何事情
