Yes, this was my question.
Now you have successful CMS-Tasks, but the Project have some trouble atm.

Theory have some tasks (Sherpa, or other) with a possibility for looping.
So, you need some watching.
WCG running better, but atm no constant flow of work.

Have you those CMS-Tasks finished before upgrading Virtualbox?
This is important.

Welcome,
2024-04-02 17:43:37 (6828): Hardware acceleration CPU extensions not detected. Disabling VirtualBox hardware acceleration support.
It can be, after reboot, VT-x is disabled again.
Problem two can be a conflict between Hyper-V and VT-x.
Better, to disable Hyper-V.

Have you searched in mcplots for this task,
is it successful for other volunteers?

Theory have hundreds of working tasks with difficult working parameter.
mcplots-dev must be started new from default homepage, because of revision.

In LHCatHome prefs, you can set a default for Atlas.
But, it's useful to work with an app_config.xml.
You can search in the messages for app_config.xml,
but must expand searching (default are 30 days).

Seeing the same.
What you can do is in Virtualbox for this VM, right mouse and restarting this VM.
For me it helps and restarted again.
