Hello, everyone I found something strange

I can't read this image by imRead function. But can read this image by c# function.

This is my test code.

string path = "Focus.png";

Bitmap bitmap = new Bitmap(path); //success
pictureBox1.BackgroundImage = bitmap;

Mat mat = Cv2.ImRead(path, ImreadModes.Unchanged);
 Cv2.ImShow("test", mat); //error
 Cv2.WaitKey(0);

I don't have any idea about this issue. Could you help me?

The image was taken from the machine vision camera in use. Other images were normal. Only the image was not normal.
