Azure应用程序已从对COM组件的调用中返回HRESULT E_FAIL

我有一个基于websocket的文本编辑器，是为一个大学项目编写的。在我的本地计算机上运行良好，但当部署到Azure时，我会收到一个错误。

问题出现在将html转换为rtf时，我使用了这里和这里的混合代码。这需要在单线程公寓中使用windows窗体组件，这有点令人头疼，但它确实有效。。。直到我迁移到Azure。

在Visual studio中调试时，我收到错误消息：

System.Runtime.InteropServices.COMException was unhandled
  ErrorCode=-2147467259
  HResult=-2147467259
  Message=Error HRESULT E_FAIL has been returned from a call to a COM component.

在这里可以找到有问题的代码，异常发生在"tempBrowser.DocumentText=data.html；"行

using System;

namespace RealTimeTextEditor

    public class HtmlRtfConvertor
    {
        public void ThreadConvertor(string inputpath, string inputhtml)
        {
            var t = new Thread(ConvertHtmltoRtf);
            var dataForConversion = new ConvertorData { path = inputpath, html = inputhtml };
            t.SetApartmentState(ApartmentState.STA);
            t.Start(dataForConversion);
            t.Join();
        }
        public static void ConvertHtmltoRtf (object obj)
        {
            var data = obj as ConvertorData;
            using (WebBrowser tempBrowser = new WebBrowser())
            {   
                tempBrowser.CreateControl();
                tempBrowser.DocumentText = data.html;
                while (tempBrowser.DocumentText != data.html)
                {
                    Application.DoEvents();
                }
                tempBrowser.Document.ExecCommand("SelectAll", false, null);
                tempBrowser.Document.ExecCommand("Copy", false, null);
                using (RichTextBox rtb = new RichTextBox())
                {
                    rtb.Paste();
                    rtb.SaveFile(data.path);
                }
            }
        }
        public class ConvertorData
        {
            public string path { get; set; }
            public string html { get; set; }
        }
    }
}

调用html转换器类的控制器代码：

        HtmlRtfConvertor convertor = new HtmlRtfConvertor();
        convertor.ThreadConvertor(path, html);
