Ca't open generated dcument with image

[anatoly-kryzhanovsky]

good day i have some trouble and need assist i have test html markup:

<h2>Sample</h2>
<p><span class=""text-big"" style=""font-family:'Courier New', Courier, monospace; "">row </span><span class=""text-tiny"">with </span><span class=""text-big"" style=""color: hsl(60, 75 %, 60 %); "">different </span><span class=""text-big"">text </span><span class=""text-big"" style=""background-color:hsl(120, 75 %, 60 %); "">formats</span></p>
<p>This is an instance of the <a href=""https://ckeditor.com/docs/ckeditor5/latest/builds/guides/overview.html#classic-editor"">classic editor build</a>.</p>
<figure class=""image""><img src=""https://image.shutterstock.com/image-photo/beautiful-water-drop-on-dandelion-260nw-789676552.jpg"" alt=""Autumn fields""></figure>
<p>You can use this sample to validate whether your <a href=""https://ckeditor.com/docs/ckeditor5/latest/builds/guides/development/custom-builds.html"">custom build</a> works fine.</p>

i try to insert converted paragrahs to my document:

var converter = new HtmlConverter(document.MainDocumentPart);
converter.ImageProcessing = ImageProcessing.AutomaticDownload;
var parsedData = converter.Parse(content);
foreach (var itm in parsedData)
	position.AppendChild(itm);

but then i try to open document with wrd (2016) i receive error:unspecified error: part: /word/document.xml, Line: 0, Column: 0

i try to skip paragraph with image and document open correctly. i also look at document.xml inside docx and where is no other difference for document with image and without it...
