Display managers not working
Hi! Yesterday I updated the packages on my arch32 Lifebook T4215 (ran "yay -Syu") and when I rebooted the laptop it got stuck right after the "/dev/sda: clean, .../... files, .../... blocks" part (i'm not sure what that's called) and showed just a black screen with a blinking cursor. I could switch to tty2 and login in terminal mode and find that lightdm had failed to start?
I tried to uninstall it and try other display managers, figuring something had broken in the package update (i'm not even sure if i updated lightdm or lightdm-gtk-greeter), but emptty and cdm didn't work either, so i figure the problem is deeper than just lightdm.
I can launch i3 using "xinit /usr/bin/i3" but most programs return with an error like "libicu__.so.75: cannot open shared object file: No such file or directory". I suppose this has something to do with the gui since it doesn't raise this error for console programs, but I don't know what this means.
Here is the output of "sudo journalctl -b" having lightdm installed. You can see how it attempts to create a session for lightdm but deletes it immediately, which it repeats 10 times:
...

...
The only thing that stands out to me is the "The name is not activatable" error lightdm is throwing. ¿Is that the problem here? I can't find how to fix any of this. I'm at a loss here, this laptop was working (mostly) perfectly yesterday and I'm not smart enough to get what is going on. Do you need any more logs?
