'Tis the usual. Hyper-V needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

I have already disabled Hyper V

Virtualbox doesn't think so:

00:00:04.205032 HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
00:00:04.268492 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

"Hyper-V" is not the only thing in Windows 10 that uses Hyper-V, and "Disabling Hyper-V" therefore does not always truly disable Hyper-V.

If you fully followed the posted tutorial before posting the above, run the guest again and check the guest's vbox.log for the words "Attempting fall back to NEM". Copy/paste them into the Find box. If these words are still there, you didn't disable Hyper-V. Try the tutorial again carefully.
