Make sure Virtualization is enabled in all places in bios\efi, make sure Hyper-V, Windows Subsystem for Linux, Windows Sandbox, Windows Hypervisor Platform, and all Windows security settings involving virtualization are disabled. If that error is showing up it means something is still using Hyper-V or is using its own virtualization features that is locking the system
