From my previous post, I was using Android Emulator Hypervisor Driver for AMD Processors but recently I am trying to do things with Docker, that requires Hyper-V on Windows. And someone pointed me to Official Docs that has an interesting table for choosing a hypervisor. It has this

You have an AMD processor and do need to run Hyper-V at the same time as the Android Emulator. Use WHPX

And it points to This section on the same page. Tl;dr is with more modern version on Android Studio (3.2 or later) and Android Emulator (27.3.8 or later), one can just use the built in Windows Hypervisor Platform to run Android Emulator when using AMD processors. This was apparently the case even when I wrote my last post. Not sure why I needed to do what I did. ¯\_(ツ)_/¯
