Question

I am working on universal windows app on Windows 10 SDK to draw rectangle on faces recognized in the image.

I am using Win2D to edit the pictures and draw rectangle on i

Answer 1

Try to access the file by the stream, not the path:

var photoFile = await KnownFolders.PicturesLibrary.CreateFileAsync("image2.jpg", CreationCollisionOption.ReplaceExisting);

if (photofile != null)
{
    using (var stream = await photofile.OpenAsync(FileAccessMode.ReadWrite))
    {
        await offscreen.SaveAsync(stream, CanvasBitmapFileFormat.Jpeg);
    }
}

In UWP if you access files via path, you will likely get Access Denied in many cases, it should be done via StorageFile.
