error: Invalid/Unknown/Unsupported format

[NirmalTest]

Good Day,

Getting this "error: Invalid/Unknown/Unsupported format" while using LoadFromFile method in Ubuntu but same works in windows

PdfDocument Document = new PdfDocument();
Document.LoadFromFile(Path.Combine(downloadLocation, fileName), FileFormat.PDF);

Am using Spire.PDF - Version 9.2.6 and even tried with 10.1.1

Please let me know if any workaround. Thanks in Advance
