Unable to login - login process crashes

When logging in using the tty, I am able to type in my username and password, but when the login is successful, the login reverts back to the previous prompt. Booting in through live usb, I uncovered that

When the login is not successful, the login process doesn't crash and displays the normal message.
This happens both on the root and regular user.
Help?

Make sure there's no partial upgrade (run "pacman -Syu"), try whether you can autologin, https://wiki.archlinux.org/title/Getty# … al_console
If so, try to su from there and whether that crashes as well.

From the context, it *could* be due to https://wiki.archlinux.org/title/Enviro … ng_pam_env - https://bugs.archlinux.org/task/67636
