word experienced an error trying to open the file Error

[saamtehraani]

I have tried to convert HTML to OpenXML. When I want to open the generated file I get this error:

This is my code:

                string background = ((dynamic)obj).Entity.Background as string;                    
                HtmlConverter converter = new HtmlConverter(mainDocumentPart);
                IList<OpenXmlCompositeElement> convertedToHTML = converter.Parse(background);
                List<OpenXmlElement> openXmlElementList = new List<OpenXmlElement>();

                convertedToHTML.ToList().ForEach(q =>
                {
                    var convertedOpenXmlElement = q as OpenXmlElement;
                    openXmlElementList.Add(convertedOpenXmlElement);
                });

                addAction(new Run(convertedToHTML.ToList()));
