System.ArgumentException: 'Parameter is not valid.' (showDialog error)

[Haters]

Hi, I am new to c#, I am trying to code a page where select a button it will pass the image and its text to the other page, however, it shows me this error. (I was having an error with the code in bold and underlined )

An unhandled exception of type 'System.ArgumentException' occurred in System.Drawing.dll
Parameter is not valid.

(The first code was the image and message to be inserted)

(The second code was for the image and message to be inserted into the first code)

  

  First code

 public Booking(Image passingimage, string bandtitle)
        {           
            InitializeComponent();
            pictureBox1.Image = passingimage;
            bunifuCustomLabel5.Text = bandtitle;
        }

  public static void Shbooking(string bandtitle, Image passingimage)
        {
            Booking bk = new SoftwarePrj_LawZhiMing.Booking (passingimage,bandtitle);
            bk.ShowDialog();
        }

 

Second Code

   public partial class EandB : UserControl
    {

        Image passingimage;
       public static string passingtitle;

private void BunifuThinButton21_Click_1(object sender, EventArgs e)
        {
             ((Home)this.TopLevelControl).Hide();
             passingimage = pictureBox6.Image;
            passingtitle = bunifuCustomLabel2.Text;
            Booking.Shbooking(passingtitle, passingimage);
        }

     }
