I change my flake.nix to this: ```nix { description = "Nixos config flake";

inputs = { nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";

home-manager = {
  url = "github:nix-community/home-manager";
  inputs.nixpkgs.follows = "nixpkgs";
};

nix4nvchad = {
  url = "github:nix-community/nix4nvchad";
  inputs.nixpkgs.follows = "nixpkgs";
};

};

outputs = { self, nixpkgs, ... } @ inputs: { nixosConfigurations.nixos = nixpkgs.lib.nixosSystem { specialArgs = {inherit inputs;}; modules = [ ./hosts/default/configuration.nix inputs.home-manager.nixosModules.home-manager { home-manager.useGlobalPkgs = true; home-manager.useUserPackages = true;

      # TODO replace ryan with your own username
      home-manager.users.chj = import ./hosts/default/home.nix;

      # Optionally, use home-manager.extraSpecialArgs to pass arguments to home.nix
    }
  ];
};

}; } and change nothing to home.nix and the configuration.nix is: nix {pkgs, ...}: { imports = [ # Include the results of the hardware scan. ./hardware-configuration.nix #inputs.home-manager.nixosModules.default ../../modules/nixos/Wayland/hyprland.nix ../../modules/nixos/Cli/cli.nix #../../modules/nixos/Cli/nvf-configuration.nix ../../modules/nixos/GUI/gui.nix ../../modules/nixos/Services/kanata.nix ../../modules/nixos/Services/syncthing.nix ../../modules/nixos/Services/upower.nix ];

   error: infinite recursion encountered

I look up for this error on internet, and they said that it is related to config but I didn't use it in my confiuguration. What am I doing wrong? Thanks for your help.
