No administrator was found

I wanted to run a Windows to go on my new MacBook Pro 2018 with an external drive, because it has the Apple T2 chip (About Startup Security Utility - Apple Support), I have to run the Startup Security Utility to allow booting from external media.

But when I see the macOS Utilities window, and choose Utilities > Startup Security Utility from the menu bar, it asked me to Enter macOS Password. When I clicked it, it said that "Recovery is trying to change system settings. NO administrator was found."

Actually I do have an admin account on my Mac and I don't know why it happened.

MacBook Pro (15-inch, 2018), macOS High Sierra (10.13.6)

OMG....A board replacement? What if I can't afford that?

Im just trying to get rid of the security lock to reinstall Mac OS. Why does apple do this to people?

Not even terminal commands will work?
