I am from Spain so am Using W10 Home Spanish version
Unknow how I get Hyper-V active, probably trying to instal Microsoft Sandbox with the sandbox-installer.zip
file at Deskmodder (which did not work either).
My VM VirtualBox went south after that and I have spend three days reading and trying lots of non-working solutions.
Luckily I have found one that has restored my virtual box
In a Powershell window opened as Administrator
bcdedit /set hypervisorlaunchtype Off
reboot two times. I did them as cold reboot (unswitching computer from mains more than 10 seconds)
Hope it work for you too
