I'm a Devuan.org maxi now after several similar experiences, but with debian rather than ubuntu.
The old-timers knew what they were about with the "unix principle", that SystemD is the antithesis of. However well-executed, it is an anti-pattern.

I usually don't do updates, but apparently libre office had an auto update feature i didn't disable and it just scrambled the OS. wtf lol i thought ubuntu was stable.
Ubuntu always used to be! Its what I set up for my dad when he asked for a Linux box at age 66 lol.
so the problem you have is that the libraries you have on the system are not at the same level and there is a conflict. You should have done the updates. Now if you do the updates it might get fixed but also it might break. Backup what you need to.
Did you do the updates? Did you had any programms installed that were not on the repositories?
I do regular automated updates, but yes I also install software outside the package manager. I prefix it to /opt subfolders to prevent clobbering.
I still use Debian for ARM architectures, Devuan can be tardy there.
