Android Studio Emulator is not working on Windows 11 when WSL2 is installed

Issue

Setup:

• Windows 11 Home 21H2 22000.132
• AMD Ryzen 5900X
• WSL2
• Android studio lastest build (also tried with latest beta)

Problem: As soon as I install WSL2, the emulator stops working. It's giving the following error message:

C:\Users\gusta\AppData\Local\Android\Sdk\emulator>emulator.exe -avd Android_TV_1080p_API_300
emulator: Android emulator version 30.8.4.0 (build_id 7600983) (CL:N/A)
handleCpuAcceleration: feature check for hvf
added library vulkan-1.dll
Failed to open /qemu.conf, err: 2
C:\Users\gusta\AppData\Local\Android\Sdk\emulator\qemu\windows-x86_64\qemu-system-x86_64.exe: WHPX: Failed to setup partition, hr=c0350005
C:\Users\gusta\AppData\Local\Android\Sdk\emulator\qemu\windows-x86_64\qemu-system-x86_64.exe: failed to initialize WHPX: Invalid argument

Using WSL2 at the same time as the android emulator was working before on an Intel i7 4770k processor, but stopped working after a processor upgrade to a AMD Ryzen 5900x and fresh install of Windows 11.

For clarification: I'm not trying to run the emulator from WSL2, I'm trying to run it from Android Studio. When trying to start it from Android Studio it never launches, when trying to run it from the Windows Command Line I get the above error.

The "Failed to open /qemu.conf" is possible to solve by creating that file manually, as explained by this answer. That however doesn't fix the two later errors with WHPX.

I've followed the official instructions on this page (Following the AMD with Hyper-V option WHPX). I think the problem has to do with Hyper-V running which WSL2 is using if I'm not misstaken. But according to the above link it should be possible to run the emulator at the same time as Hyper-V using WHPX. I've also tried using the Android Emulator Hypervisor Driver for AMD processors, which is giving me the exact same result.

Thankful for any help, and please tell me if I need to add more information

Solution

I finally got this working using this fix (answer number 48). Seems like a valid workaround until windows fixes this issue. I downloaded the compiled version for windows and moved it to my emulator path C:\Users\<username>\AppData\Local\Android\Sdk\emulator. Seems to be versions available for linux and mac as well but I haven't tested those.
