"Parameter is not valid." in System.Drawing.Bitmap

Question

I built simple application to take full screenshot each 100ms of computer's screen and set the screenshots on the PictureBox :

 

private void StartWork()
      {
          try
          {
// width :1916 and height :1074 is the best measure to take full screenshot of whole laptotp's screen
              using (Image bitmap = new Bitmap(1916, 1074))
              {
                  using (Graphics g = Graphics.FromImage(bitmap))
                  {
                      g.CopyFromScreen(Point.Empty, Point.Empty, new Size(1916, 1074));
                  }
                  pictureBox1.BackgroundImage = (Image)bitmap.Clone();
                  pictureBox1.BackgroundImageLayout = ImageLayout.Stretch;
                   //Sending Function to Send every token screenshot to all connected TcpClients
                 // Sending(bitmap);

                  pictureBox1.Invalidate();
                  pictureBox1.Refresh();
              }
          }
          catch (Exception ee)
          {
          //    MessageBox.Show(ee.Message);
          }
      }

 calling StartWork() in every 100ms in Tick event :

private void timer1_Tick(object sender, EventArgs e)
      {
          StartWork();
      }

it is run well and i see the screenshots appears on PictureBox one after one but after several seconds I am facing this exception :  

Data = {System.Collections.ListDictionaryInternal}

HResult = -2147024809

 Message = "Parameter is not valid."

Source = "System.Drawing" 

 StackTrace = " at System.Drawing.Graphics.GetHdc()\r\n at System.Drawing.Graphics.CopyFromScreen(Int32 sourceX, Int32 sourceY, Int32 destinationX, Int32 destinationY, Size blockRegionSize, CopyPixelOperation copyPixelOperation)\r\n at System.Drawing.Graphics.CopyF...

TargetSite = {IntPtr GetHdc()}

 

I was searched in simillar problems in  CSharp Corner and Stackoverflow and try to change a lot of things but really i becommed tired.
