I'm getting Atlas errors and I'm wondering if it's my machine that's misconfigured. To me, it looks like something wrong with Atlas internally, but I'm not sure.

So far I've had 3 tasks fail.

I have started to get a lot of validate errors, here's one: https://lhcathome.cern.ch/lhcathome/result.php?resultid=435642726
This is on a Windows 11 machine with VirtualBox and freshly downloaded tasks. The same error seems to be also on all other hosts that have crunched the same tasks.

I don't see these errors on my WIndows 10 host that is still crunching tasks that it downloaded 2 days ago.

I think you are correct that its a config error in the ATLAS tasks themselfs.

I don't see any error tasks just invalids but everyone that got the WU also got invalid.

Same here. Switched back to Theory.

since this problem has been existing for quite some time, I am surprised that no one from the project team has noticed yet

Yup, I have started to get validate errors also.
