I installed pandoc-eqnos on Windows 10 using pip install pandoc-eqnos pandoc-xnos, but when I try to convert the markdown to word with --filter pandoc-eqnos I get an error:

Word experienced an error trying to open the file.
Try these suggestions.

• Check the file permissions for the document or drive.
• Make sure there is sufficient free memory and disk space.
• Open the file with the Text Recovery converter. (algorithm-update.docx)

When I delete the setting "--filter pandoc-eqnos", the word can be opened sucessfully.
