Windows 10 host black screen after boot when hyper-v is enabled

I am using Docker for Windows and everything worked fine.

Today suddenly my machine didn't boot anymore.
After a lot of fiddling around it seems to be the Hyper-V Hypervisor whats causing this.
Windows boots up but after the bios the screen turns black (but you still hear sounds etc. when connecting e.g. a usb drive).

Any idea whats causing this?

EDIT:
After downgrading my Intel HD 4600 driver it works again.

---> HYPER-V is INCOMPATIBLE with the new intel driver 20.19.15.4531 (win10, thinkpad w541).

(Also why the heck is windows updating my graphics driver?)
