If you have virtualization on in the BIOS/UEFI and still have issues there may be a possible Windows Hyper-V/ Virtualbox conflict
try disabling Hyper-V
Control Panel> Programs and Features> Turn Windows Features On or Off
Note: disabling Hyper-V will "break/disable" other hypervisors that require Hyper-V such as Native Docker for Windows
