Describe the bug

This home-manager pull request breaks rebuild:

       error:
       Failed assertions:
       - gaj profile: `nixpkgs` options are disabled when `home-manager.useGlobalPkgs` is enabled.

I have tried to set in home-manager config programs.hyprpanel.overlay.enable = false; and load inputs.hyprpanel.overlay in the main nixpks.overlays but it does not solve the problem.

To Reproduce

• update home-manager input
• run nixos-rebuild

Additional context

Stylix has a similar issue. I was able to work-around that problem by temporarly using as flake input stylix.url = "github:panchoh/stylix"; # FIXME: should be github:danth/stylix.

This solves the problem on my nixos configs that do not use hyprpanel.
I have 2 configs that are virtually identical, except one uses i3 and polybar (which builds fine), and the other uses hyprland and hyprpanel (which has the build error).
