New Post: No such file or directory @ error/pdf.c/ReadPDFImage/713

I'm experiencing this exact same issue starting with the first error "No such file or directory" and now getting "Object reference not set to an instance of an object" when converting a PDF to a png vertically. Did you guys resolve this?

                        ImageMagick.MagickImage vertical = images.AppendVertically();
                        vertical.Write(destinationFilePath);
