        {
           
                currentFrame = camera.QueryFrame().Resize(440, 330, Emgu.CV.CvEnum.INTER.CV_INTER_CUBIC);
                currentFrame.Flip(Emgu.CV.CvEnum.FLIP.HORIZONTAL);
                gray = currentFrame.Convert<Gray, Byte>();
                camera.SetCaptureProperty(CAP_PROP.CV_CAP_PROP_FRAME_WIDTH, 640.01);
                camera.SetCaptureProperty(CAP_PROP.CV_CAP_PROP_FRAME_HEIGHT, 480.01);

With code that does not show how you attempt to connect to the camera, and does not show definitions of variables like 'face ... how are we supposed to assist you ?

camera = new Capture(1);
camera.QueryFrame();

with this code

This code won't compile so I don't understand how you can have had it working. It looks like code you've copied from somewhere else without actually understanding. The issue might be

camera = new Capture(1);

that will get a reference to the second camera device attached. If you're trying this code on a different machine with different number\configuration of cameras then "1" might not longer refer to the camera you want, it might be "0" or some other number.
