Since the installation of 22.9.0.68, the Background tasks (Settings, Administrative settings, Background tasks/Configure) do not run by themselves. This includes the 4 "greyed" out maintenance tasks at the bottom of the list and Automatic liveupdate.
The performance usage graph does not reflect any activity, it now shows a static screen of 90 minutes of "Sleep" and no cpu activity at all.
LiveUpdate has been run manually multiple times and the pc was restarted numerous times but it doesn't help.
