We recently updated our Ubuntu systems to 22.04.1 at work. These machines are used to run code by multiple users at a time. Since the update, one of the machines no longer allows multiple users to be logged in at a time (i.e. using "switch user"). If we do, we get to the login screen, but end up in a login loop except for the user already logged in. If we use the "log out" option, another user can login, but that would interrupt anything running in the meantime. The other machine works without problems.
One other thing to note is that ever since, when trying to power off the machine in question, it warns that "another user is signed in" and gives the current user as the other user.
I've looked around, but didn't find any solution as of yet. Thanks in advance for any help!
