Can I access an unrecoverable document?

I am currently using LibreOffice writer, I’m not sure what version, I believe it’s a little older. Anyways, before I had a chance to save my document, my computer shut down. I tried to do document recovery but it said it failed, and then it tried to repair the file but that didn’t work either. I was wondering if I could ever access this document again?

Which computer is this on?

If it was a Mac and you are running Time Machine, you should be able to recover a slightly older version of the file with it.
