using (PdfDocument two = PdfReader.Open("C:\\Downloads\\Page2.pdf", PdfDocumentOpenMode.Import))
using (PdfDocument outPdf = new PdfDocument())
{
CopyPages(one, outPdf);
CopyPages(two, outPdf);

outPdf.Save("C:\\Documents\\NewFileTest.pdf");
}

Will be fixed with the next version.
Does not occur when using .NET 6 instead of .NET 4.7.2.
