AMD-V is not available (VERR_SVM_NO_SVM)

Try :

To ensure Hyper-V is totally disabled, enter in elevated Command Prompt:
```
bcdedit /set hypervisorlaunchtype off
```
Run gpedit.msc and go to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security, and set to Disabled. Do the same for CredentialGuard.
Check Windows Defender Security Center > Device Security > Core Isolation Details, that it is turned off.

This problem happened on my Windows 10 build 1903 after I enabled Windows Sandbox in Windows features. It was solved after I uninstalled it.
