EMERGENCY Word file can't be opened?

I have the automatic OneDrive save. I was typing and then my laptop went off. After I turned it on again, it said that the last changes were yesterday. Still, I couldn't open the file at all. Neither by One drive nor by Word… I've tried everything possible but it doesn't work. If I click yes or no the same thing happens. Again and again this message and empty document. Does anyone know and can help me? You're welcome

Press yes when asked if you want to restore the file.

Press yes

I did and it still doesn't work. The message in the picture is shown again and again

Then try to upload your file to a word to PDF converter on the Internet and download it as a PDF file.

This indicates that the file is damaged
