Comment 108 for bug 1951491

So I had this same issue on two machines that are running Ubuntu 22.04.4 LTS Desktop with more or less the same software installed.

I run `sudo apt update && sudo apt full-upgrade -y && sudo apt autoremove -y && sudo apt autoclean && sudo apt clean && sudo snap refresh` when I haven't been on any machine for a few days. I execute that command in the terminal app right after I start my desktop session.

After that command firefox does not start. Slack shows a window for a brief second and then disappears. After a few re-clicks on the program in the start menu they both start again. While slack does completely exit a few times after it started, after 3 to 5 times it recovers and starts acting like it normally does.

Errors I see related to cgroup:
```
systemd[29657]: app-gnome-gnome\x2dkeyring\x2dsecrets-29897.scope: Couldn't move process 29897 to requested cgroup '/user.slice/user-1000.slice/user@1000.service/app.slice/app-gnome-gnome\x2dkeyring\x2dsecrets-29897.scope': No such process

```

I have a hunch that something is in a wrong state after `sudo snap refresh` maybe in combination with the updates installed by `sudo apt full-upgrade`.

Let me know which kind of logs you like me to share.
