You could use Proton from Steam. Just tested this and can confirm it works. Here’s your guide.

1. Download PrimeHackUpdater.
2. Add the exe to Steam as a non-steam game, and select Proton in compatibility options.
3. Open it up with Steam. Just click Never on the prompt for now.
4. You’ll see Dolphin, hooray. Close it for now. You’ll notice in the folder you had the updater now exists a bunch of Dolphin files.
5. Go back to Steam. Add the dolphin exe that exists here to Steam and use Proton.
6. Open Primehack/Dolphin on Steam. Go to the graphics options and change it from DX11 to Vulkan or OpenGL.
7. Enjoy.
