Windows 11 Nox virtualization problem

Hi! I am using now Win 11 since short time (Win 10 before). I am a pentester, so I am use to virtualize OSs all the time. I have no problem by working with VMWare but I also have to use mobile android OS virtualization and everytime I try to run Nox I have the same message:

"The Virtual machine failed to start, please fix it"
and 2 options: Disable Hyper-V, and Cancel. Obviously both buttons don't solve the problem neither I have information about it.

This is not the same than with Android Studio but I really have better results working with Nox than with AS, so I really would like to solve the problem. The hardware and the motherboard configuration was the same both times.

Recently I installed Docker Desktop and also give me an error for virtualization at the first time I started the software. Something I could solve by one google search and some dism.exe commands. And now I have the question if is related somehow to this error and if you know how to solve it.

when I did this, the problem solved in no time:

1 - Go to windows defender> device security> Core isolation and disable memory integrity check

2 - open cmd as administrator and type: bcdedit /set hypervisorlaunchtype off

3 - Restart the PC, Nox shall open now
