In one of the newer builds of Windows 10 Hyper-V is always on because it's used to provide added security to the OS. You can only have a single hyper visor running and since Hyper-V is a hyper visor you can't run Virtualbox. You can use hyper-v to setup and run VMs though.

Have you already tried this?

I encountered this same error (rc=-5640) numerous times on various Oracle Virtual Box versions, and I installed and reinstalled it repeatedly, but it did not work. The latest version I tried was 7.0.20

I managed to solve it by starting the Guest VM using "Headless Start" or "Detachable Start."
