A family of Microsoft word processing software products for creating web, email, and print documents.
I think I get the solution. When the issue started, I reviewed the OneDrive configuration and I see marked the first two options, "Use Office to sync Office files" and "use office 2016 to sync Office files that is want to open" or somethings like that. My OneDrive app are in spanish. When I unmark the Office option (I let the Office 2016 option marked) Word works like a charm!
Even, if you unmark the two options, Word works flawless. Please, try it and let me know if that's works to you.
Best regards,
