You need to clear some disk space and get it working again, maybe run a fsck. Usually after doing so even with ext2/3/4 it'll boot again, but it gets a weird hard lock when full that buggers it. Lovely behaviour.

Using LVM, even filling a working disk I can work with it, where I can't with a raw partition. No idea why, but just a fact I've run into many times. Figure a limitation or quirk of the FS.

If another system available, offload your user directory, particularly .config and your libreoffice files within to launch externally and restore work, even temporarily to get back up. Clearing space might work in general if you can figure out what is filling up your disk.

Thanks Michael.

Yes, I do realize that I probably need to build a
completely different system, but for now, I just
have to find ways to keep my old system working.

Now, after a reboot, I have most everything working
again, but for now, I mainly just need to find out
how to unlock Libre Office documents.
