Combining Word Document to Single Pdf Document

I've been using Adobe Acrobat for about six months primarily for tasks like text recognition, file merging, and PDF editing—typical university-level work.

Recently, I've encountered a problem where Adobe isn't accepting my Word documents. When I try to use the 'Combine Files' feature and select the documents, Word displays an error message, and Adobe Acrobat freezes, causing both applications to crash. Despite uninstalling and reinstalling both Word and Adobe multiple times, the issue persists.

Please help; this situation is becoming exasperating.
