How do I reinstall LibreOffice?

The latest update on my Mac wiped out my ability to open my document files that I wrote in LibreOffice. How do I get back what I had before? Thanks

The latest update on my Mac

… “update” of what? Update of macOS to Big Sur? Update of LibreOffice to a new version (which old version to which new version)?


Which version of LibreOffice do you have installed? Why do you want to reinstall, if you don't know anything about the problem (reinstalling is **not** the first but the last resort in trying to fix a problem). Many problem esp. on macOS cannot be fixed by reinstalling LibreOffice (though you might need a new LibreOffice version **if** you had version less than 7.x **and** updated macOS to Big Sur), but require some other settings like there are:
  • provide Full Disk Access to LibreOffice.app
  • reset LibreOffice user profile
