The code you shared in your previous post is causing a few compile time errors on our end. For example, we are unable to resolve assembly reference of type or namespace TextFieldParser on our end. It would be great if you please create a simplified standalone simple console application (source code without compilation errors) that helps us to reproduce your problem on our end and attach it here for testing. Please do not include Aspose.Words.dll files in it to reduce the file size. You can ZIP the project and attach it. You can also upload the ZIP file to Dropbox and share the Download link here for testing. Thanks for your cooperation.
Have you also tried the latest version of Aspose.Words for .NET i.e. 19.12 on your end. Instead of saving to PDF, please save the final output in DOCX format, ZIP it and share the DOCX file here for further testing.
