With the library version 24.06 the code

var fileFullPath = dataDir + "1-out.pdf";
var sourceFullPath = dataDir + "task-544.html";
// Create a HTML LoadOptions
var options = new HtmlLoadOptions();

// Set Print or Screen mode
options.HtmlMediaType = HtmlMediaType.Print;

var pdfOptions = new Aspose.Pdf.PdfSaveOptions();
// Initialize document object
var document = new Document(sourceFullPath, options);

// Save output PDF document
document.Save(fileFullPath, pdfOptions);

works without exceptions. The result is valid.
I am attaching a document obtained when using the library without a license.
1-out.pdf (1.7 MB)
