Specifically: in Android Studio when setting up a virtual device I get the warning "Android Emulator Hypervisor Driver for AMD Processors is not installed."
Okay, here's what I've tried:
Clicked the link "Install Android Emulator Hypervisor Driver for AMD Processors" and got the following:

So I go to Github. It advises 2 things:
1 - CPU has virtualization extension and BIOS has NOT disabled the extension.
Went through my entire BIOS, couldn't find any mention of virtualization anywhere. I'm running an AMD Ryzen 7 2700 Eight-Core Processor if that matters.
2 - Hyper-V must be disabled. Refer to this page for more information.
From that page I double-check my current Features, no problem there: https://i.sstatic.net/tOJXa.jpg
And under Windows Security they show a screenshot of a section called "Core Isolation"... which I don't appear to have. My page looks pretty different: https://i.sstatic.net/A70nW.jpg
As a last-ditch they advise a little CPUID utility, which I ran from a CMD window with Administrator privileges. The results are... good? I guess? https://i.sstatic.net/ljihR.jpg
Someone mentioned somewhere that Windows Update can help and hurt this so, whatever, I ran update a few times. It's as updated as it can be. Rebooted, repeated the above. Still no dice.
Oh and no, I'm not running AVG.
Also, following up on advice from other threads:
I changed my Emulated Performance - Graphics to "Software". Doesn't make a difference.
Someone advised editing the .ini of the actual virtual device but that didn't seem to improve things.
Someone else gave a command for making sure the emulator never uses hardware acceleration but... okay that part, full disclosure, I didn't understand the instructions.
Any other advice?
As per Tobias' comment, enabling virtualization in the Bios fixed this for me. This meant enabling SVM in my BIOS advanced settings.
