[Bug]: can't create bottle if vulkan is unavailable

[fatmalama]

Describe the bug

I've tried creating bottles on a system that doesn't have vulkan available - an AMD A4 with AMD ARUBA Radeon 7480D (TeraScale). It seems to hang trying to install vkd3d of which I find no way to specify I don't want. I've also tried modifying a backed up bottle config.yml to set to false vkd3d and dxvk but it fails too on self.vkd3d_available[0]

To Reproduce

1. Try creating a bottle on a system without vulkan or try to import a config file with all vulkan related stuff set to false

Package

Flatpak from Flathub

Troubleshooting Logs

Additional context

this is what I get when I tried importing the config.yaml setting the vulkan related bits to false:
