Can't get Obs Studio to work or open

Here is what’s in my configuration.nix file as it says it should be on wiki.nixos:

programs.obs-studio = {
enable = true;
plugins = with pkgs.obs-studio-plugins; [
wlrobs
obs-backgroundremoval
obs-pipewire-audio-capture
];
};

Obs is listed in my ‘applications’, but it won’t open. I am new to using OBS, I tried to cli as well. GUI = XFCE

And what is the error?
