Bluestacks Hyper-V not disabling

i recently tried to install Bluestacks on windows 10 pro (x64) and upon installation i am greeted by the "Bluestacks is unable to use hardware assisted virtualisation when hyper-v is enabled". Even though i have disabled "windows sandbox", "Windows hyper visor platform", "Virtual machine platform" and "Hyper-V", i also have Intel virtualisation technology enabled in the bios. i have also checked to make sure that core isolation is off in my device security settings but i keep on getting the same error. any ideas?

EDIT: my cpu is the i7-4790

After making sure the CPU Virtualization is enabled, best to uninstall Hyper V by

1. Start > search and click Turn Windows features on or off,
2. Uncheck Hyper V main node and click ok (will uninstall the hyper V feature)
3. Restart PC
4. cmd > systeminfo
   • if it says something like 'a hypervisor has been detected', bluestacks will still get the issue so run 'bcdedit /set hypervisorlaunchtype off' to disable hyper V completely

• else, congrats bluestacks has no hyper V issues anymore

Took me like 2 hours of installing, uninstalling, reinstalling and googling trying to find out whats going on

Here is what worked for me, in the order I tried. The last step I figured out on my own:

1. Uninstall other hypervisors like VirtualBox

2. Remove the following Windows features:

   • Hyper-V
   • Virtual Machine Platform
   • Windows Hypervisor Platform
   • (maybe) Windows Sandbox
   • (maybe) Windows Subsystem For Linux

3. Disable Windows Security> Device Security> Core Isolation: Memory Integrity

4. (Possibly unrelated to your scenario) Uninstalled Bluestacks 5 with this tool

5. (What finally worked) Disable Microsoft Defender Device & Credential Guard and all other virtualization-based security features: There are a number of sketchy tutorials but I used this script

   ...with these parameters: DG_Readiness_Tool_v3.6.ps1 -Disable -AutoReboot

Note, you are disabling security features and all that implies.
