Word won't save text into an PDF file

Hello,

I was creating a Word file and I want to save it as PDF.

When saved, the PDF had as many pages as the word file, but was blank.

I tried print as pdf, uploading it to OneDrive and saving as pdf... even a docx to pdf converter.

Always the same result.

Okay, maybe the file was corrupted.

So I wrote a short test document and saved it as pdf. It was also empty. Now every file I save is empty.

I'm so lost now.....

Thank you for your help!
