I tried disabling Windows Subsystem for Linux (WSL), Windows Defender Application Guard, and Hyper-V, but even THAT didn't work. I always disable virtualization to run Bluestacks, but now I need to enable virtualization for the new Bluestacks N version. I really want it, but Bluestacks keep saying that Hyper-V is enabled on my system and I have to review the FAQ to disable it. I also set hypervisorlaunchtype to off using bcdedit.
EDIT: Even Google's Android AVD manager reports the same thing!
