Emergency help!SGX suddenly unavailable

SGX suddenly was unavailable, the day before was still good. My SGX is installed under ubuntu18.04.

Tip :

" Info: Please make sure SGX module is enabled in the BIOS, and install SGX driver afterwards.
Error: Invalid SGX device. "

Have tried the following solutions: 1.Upgraded BIOS, no use  2.Reinstalled the SGX driver under Windows, no use  3.Reinstalled the latest version of SGX, no use . 

Please help me, what should I do? Thank you very much.

I have reinstalled the Ubuntu and still have this problem. What is the reason? How to deal with it? Emergency help! Thank you!

Error message suggests that your SGX device (/dev/isgx) is missing/damaged.

Reinstalling SGX driver should help, but make sure to first actually uninstall it, as per instructions here: https://github.com/intel/linux-sgx-driver#uninstall-the-intelr-sgx-driver .

Still, if you wiped OS then possibly you have recreated /dev/isgx and it still didn't help. In such case, what is your output after running this: https://github.com/ayeks/SGX-hardware ?
