Windows 10: Hyper-V subservice causes Blue Screen on Windows 10 1903

I have Windows 10 1903 with Ryzen 7 3700X CPU and Gigabyte X570 Aoruse Elite motherboard. When I try to manually start service with a name "Usługa obliczeniowa gościa funkcji hyper-v" (sorry I am unable to translate it, it might be something like "Hyper-v guest calculation service") OS crashes and shows Blue Screen. Why? Here you can find video: https://streamable.com/8ysm3 What information do you need to diagnose the root of the problem?

Hyper-V machine freezes on start after 1903 update

Since updating OS to version 1903, my Hyper-V machines freeze at start for about 20 seconds, then re-open login page, then it boots fine and all is good.

I've updated graphics drivers, gone through several Windows-based scans, i.e. sfc /scannow, etc.

I've also tried...

Stopped/restarted Container service

Disabling/re-enabling Hyper-V

Any suggestions?
