我在C#中有多个表单，当我调试时，不会显示更多表单

我对C#相当陌生，但是当我尝试调试我的程序时，什么都没有显示。我有多个表单，第一个表单只是一个菜单，所以我可以转到其他表单

这是我的

表格1.cs

：

namespace EscapeLabryinth
{
    public partial class frmMainMenu : Form
    {
        frmGameMenu secondForm = new frmGameMenu();
        frmHowToPlay thirdForm = new frmHowToPlay();
        Music bgMusic;

        public frmMainMenu()
        {
            InitializeComponent();
        }

        private void btnPlay_Click(object sender, EventArgs e)
        {
            secondForm.Show();
            this.Hide();

        }

        private void btnInstru_Click(object sender, EventArgs e)
        {
            thirdForm.Show();
            this.Hide();
        }

        private void btnQuit_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }

        private void btnAudio_Click(object sender, EventArgs e)
        {

        }

        private void frmMainMenu_Load(object sender, EventArgs e)
        {
            //Create a new Music object to play the background music
            bgMusic = new Music(Application.StartupPath + @"\resources\music\eurekaost.wav", true);

            bgMusic.LoopPlay();
            bgMusic.SetVolume(-100);

        }
    }
}

这是同一表单的设计器：
