Issue with conversion .docx (with table of content) to .html


I’d like to report an issue with conversion .docx to .html.

When I try to get first 7 pages or less the component works fine,
but when I try to get first 10 pages component throws an exception.

The problem seems to be with document’s “table of content”, because when I remove it component works fine even for much bigger documents.

Example .docx document is attached. (37.3 KB)

System.InvalidOperationException: Stack empty

There was a similar issue:

Component is for .NET v18.10

Can you please advise me?

Kind regards
