Same problem for me. I can't start KDE anymore!
I experienced this too and fixed it temporarily by changing my shell from Fish back to Bash from a different TTY. I was then was able to login no problems.
Are you also using Fish shell, Noé and/or Floreal?
New to linux, don't know what I'm doing. Also use Fish. Linux 5.15.23-76051523-generic sddm allows password, then a dialogue shows ksplashqml has crashed (and that it doesn't have any crash details to submit?). Black screen immediately after, tty to the yescue. First encountered on Sunday's first boot after blindly apt updating on Saturday. Did a fresh install of Pop 21.10 because noob, updated 172 separate packages through apt, rebooted and tried kde-full as I had been using. Logged out of Gnome and into KDE and it worked fine, and everything I used worked as expected too. Could login/out multiple times, no issue. Reliably reoccurs on reboot. Reinstalled Pop again, repeat apt update 172 packages, reboot, kde-full, same issue. Reinstalled a third time, tried kde-standard from apt, same; could login/out okay, just refuses to work after reboot. Does this even help?
(In reply to Nate Graham from comment #4) > Are you also using Fish shell, Noé and/or Floreal? Yes I use fish. The problem was at work so I can't wait to have my PC working, so I reinstalled Neon and problem was solved. But now I have bash as default for my user and fish only in yakuake. I didn't test with fish as default.
Possibly Bug 446438?
In my case I use X11 not wayland, and I had no issue until several months. Problem appears on 21/02/2021 just after a system update
I found this bug today after upgrading my Kubuntu 21.10 installation to the latest Plasma 5.24.1. I can't start my session in either Wayland or X11 if I set my default shell to fish.
I do the upgrade on another PC where I have fish as default shell, and there is no bug here. So... fish alone is not the problem. Maybe something in fish I don't have here. Or the problem is elsewhere
After upgrading to Plasma 5.24.2, the problem is gone.

Oh, that's good to hear. Noé, how about you?
Its also fixed for me on plasma 5.24.2!
