VirtualBox 6.1.26 not seeing hardware virtualization?

Question

virtual box

The bottom line is that VirtualBox 6.1.26 does not see hardware virtualization. Processors Intel I7 7th and 9th generation. Windows 20h2.
VirtualBox uses Native Api, although I did:
1) Enabled-disabled virtualization in the BIOS

2) Enabled-disabled Hyper-V components manually and through PS

3) Reinstalled Windows several times.
And here is the funny fact that she started working twice. First run, installation of VirtualBox, machine creation... And it works. The user logged in or I updated policies - it stopped working.
The rest of the reinstallations didn't work. It didn't work right away.

4) I checked policies and settings - everything is the same with a colleague who works for him.

5) ETC all methods from query search: "Virtualization does not work in VirtualBox"

Help, gentlemen, who can come across.
If you need to give more info - ladies.

Answer 1

In order not to use the Native API, you need to disable standard virtualization tools (such as Hyper-V) from the components in Windows, as well as components that use the standard hypervisor (WSL2, Core Isolation, Windows Sandbox).
What else is there in the politicians that rolls up and affects the hypervisor - I don’t know, but something for sure from what I listed.
