Desktop Boot and Lockup

Hello guys!

I just bought a new HP Elite Mini 800 G9, and promptly installed Windows Server 2022 on it.

Everything basic works fine, all drivers are installed etc.

However, as soon as I install Hyper-V the machine refuses to boot. It freezes at the "HP Protected by HP Wolf Security" screen.

Booting in troubleshooting mode gives me "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED"

Booting into "Safe Mode" reverts the installation of Hyper-V and I get back into Windows.

I have tried enabling and disabling every setting in UEFI I could think of, from different types of Virtualization-settings to anything regarding HP Sure*, but that doesn't seem to make any difference. Another thing I found was a Biometric setting on Lenovos that made Hyper-V stop working, with the same error, though I have not managed to find a similar setting to fix it on my new HP. Windows BSOD and other problems after enabling "Enhanced Windows Biometric Security" in BIOS Setup -...

I've also tried installing the Wolf Security Agent and enabling it, hoping that any strangeness would be solved after reading this:
Hyper-V and Virtualization Based Security (VBS) Support (hp.com)

Though, what I really am expecting is that if I enable Intel VT-settings (of which there are 2) in UEFI, that should be enough.

Closest I have to what I think should work, but doesn't:
VTx: Enabled

VTd: Enabled

UCSI: Disabled

Virtualization Based BIOS Protection: Disabled

Secure Boot: Enabled

TPM 2.0: Enabled 
TXT: Enabled

Anyone have any ideas or have come across this before?
