Convert MHTML using C# on .NET 4 & Avoid File Corrupted Exception | Root Resource is not Found in a Multipart Structure

Hi, the attached MHtml file throws FileCorruptedException when it is opened with Aspose.Words 21.2 for .Net 4.
The issue is new because the same file can be opened fine with Aspose.Words 20.10.
