Fact: I recently changed my PC hardware (except OS MS Windows10 Pro x64 (no new installation), files and graphics card), I changed my Intel processor to AMD.
Action I performed: I checked in the bios if the SVM mode is activated. I also uninstalled Hyper-V which I used to use as a hypervisor.
Frequency of issue: This issue affects all VMs created before I changed my hardware and some newly created VMs.
I use VirtualBox 6.1.18
Attached is the log and a screenshot of the last VM I created and tried to launch.
Thanks in advance for your help,
Equinox

HMR3Init: Attempting fall back to NEM (Hyper-V is active)00:00:02.686166 HM: HMR3Init: Attempting fall back to NEM: AMD-V is not available
00:00:02.721153 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

Thank-you for your help.
I disabled :
DeviceGuard
CredentialGuard
Windows Defender's Core Isolation
And run both commands in terminal:
bcdedit /set hypervisorlaunchtype off
DISM /Online /Disable-Feature:Microsoft-Hyper-V
Then shutdown and after restart.
And it works now.
Thanks again.
