.NET GroupDocs.Viewer 18.10.0 Exception



We are getting the following Exception while processing (probably) excel document:

Object synchronization method was called from an unsynchronized block of code.
   at   . ()
   at GroupDocs.Viewer.Handler.ViewerHandler`1.(   )
   at GroupDocs.Viewer.Handler.ViewerHandler`1.GetPages(Stream fileStream, String fileName, RenderOptions renderOptions)

.NET GroupDocs.Viewer 18.10.0

Unfortunately, I cannot get document itself.



Thanks for contacting support.

Please create and share with us a standalone and simple console application (source code without compilation errors) that helps us reproduce your reported issue on our end. Furthermore, please share with us the problematic Excel document so that we can investigate the issue more accurately. We shall be looking forward to your response.
