[SOLVED] BIOS hangs during boot if Intel Virtualization is turned on

[Hyedwtditpm]

When Intel Virtualization from BIOS is turned on, BIOS hangs during cold boot and asks to enter the BIOS settings. Even if I don't change any settings at all, Intel Virtualization is turned off automatically, I it boots just fine, and Windows works properly. But of course, anything requires Intel virtualization doesn't work, like the new "application guard window" on Edge browser.
If I boot into BIOS and turn it on again, everything works fine until the next cold start. It hangs in the bios boot agian.

I don't even know where I should be looking. Any ideas what the problem may be?
