On .net 5 and 6 DocIO not read FileStream when Reginal format is Thai

[Krailit]

Hi,

On .NET 5 or 6 DocIO can't read html file when the Regional format is Thai (Thailand).

It will throw error System.ArgumentOutOfRangeException: 'Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'startIndex')'

public IActionResult CreateDocumentWord()
 {
            //Set Thailand culture
            CultureInfo.CurrentCulture = new CultureInfo("th-TH");
            FileStream fileStreamPath = new FileStream("Sample.html", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
            //Opens an existing document from file system through constructor of WordDocument class
            using (WordDocument document = new WordDocument(fileStreamPath, FormatType.Html))
            {
                MemoryStream stream = new MemoryStream();
                document.Save(stream, FormatType.Docx);
                //Closes the Word document
                document.Close();
                stream.Position = 0;
                //Download Word document in the browser
                return File(stream, "application/msword", "HTMLtoWord.docx");
            }
}
