The CPU supports SGX. I don't know what's wrong

What should I do?

Hi,

Please make sure you have installed the latest BIOS. 

Run dmidecode to see details about your BIOS.

Sincerely,

Thank you for your answer, I changed the CPU to  Intel(R) Xeon(R) E-2378G CPU @ 2.60GHz then the problem is solved.

It may be a CPU problem.
