Recover unsaved file

Laptop ran out of power, both files weren’t saved. After opening LibreOffice writer I had the option to recover it and so it did, it recovered a blank page. Backups folder is empty, temp folder doesn’t have much, anything I can do?

Do you have toggle File Backup ?

I turned it on now, but it was off
