Hi, I've joined the project again, and after loading tasks, boinc says (calculation error). Can you tell me what to do?

Your logs mention the root cause:
VERR_NEM_NOT_AVAILABLE

Please use the forum search to check the comments about that, e.g.:
https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=6225&postid=50724
It includes a link to the VirtualBox forum with many details.

I think the key is in the BIOS. Now I'm not getting calculation tasks.
And I really wanted to help physics.

Dear friends,
I enabled SVM mode on my computer, but it doesn't seem to work.

The issue you are suffering from is caused by Windows vs. VirtualBox.
You already got a link to the VirtualBox forum with lots of information, but it appears that you didn't follow the suggestions given there.
