Update the ubuntustudio-default-settings package (if you have not done so already). This was due to a problem that has now been resolved in the latest release: https://bugs.launchpad.net/ubuntu/+source/plasma-workspace/+bug/2003388

Just had the same problem this morning (running Ubuntu Studio 22.04.1). Yesterday, I updated a few packages including ubuntustudio-default-settings and I suspect that's where the problem came from.

I found a workaround. In the system settings, under Workspace > Startup and Shutdown > Login Screen (SDDM), I have a choice of three themes: Breeze, and two apparently identical Ubuntu Studio themes. Not sure if the duplicate theme appeared today: it may have been there previously. I selected the Breeze theme, clicked Apply, then restarted the computer. Login works normally now and the theme is fairly similar to what I was using before.

If you want to try it and don't see the Breeze theme, I think you can get it by installing the package sddm-theme-breeze.

Could the ubuntustudio-default-settings update have introduced a bug in the Ubuntu Studio SDDM theme? Hard to tell. I should mention I already had a problem with SDDM: every once in a while, the login screen would freeze. Never found a solution for that, only a workaround: open a virtual terminal (using Ctrl-Alt-F3, for instance), login, then use "sudo service sddm restart".

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
