wine-proton-9.0.3: GOG Alpha Protocol Fails to Launch

[Neko-san]

So, when using app-emulation/wine-proton-9.0.3 and creating a wine prefix then installing DXVK & VKD3D, I find that the game fails to launch almost immediately... it doesn't even spawn a window.
I find this really weird because I've launched the game before on the Steam Deck back when it first released on GOG, so I know Proton hypothetically should be able to run the game, so I don't understand why.
