I have installed Intel haxm too.

I am using AMD RYZEN 3400G. Got the same issue and i fixed it in a very easy manner.
You have to enable Windows Hypervisor Platform
Go to Control Panel> Programs > Turn Windows features on or off and check the Windows Hypervisor Platform. And yes don't install HAXM.
EDIT : 27th Aug 2019
Only install the emulator image which is stable (or one version behind). For now use Android P image not Q, since I had a problem where Android Q image was not working with HyperV & only looking to install HAXM (which we know is not possible since it is not Intel)
Note : The image must not be installing HAXM along with it, otherwise it won't work.
