evaluation warning: You are using:
                    - Nixvim version: 26.05
                    - Nixpkgs version used to evaluate Nixvim: 26.05
                    - Nixpkgs version used for packages (`pkgs`): 25.11

                    Using mismatched versions is likely to cause errors and unexpected behavior.
                    It is highly recommended to use corresponding Nixvim and Nixpkgs releases.

                    If you insist, you can disable this warning using:

                      version.enableNixpkgsReleaseCheck = false;

       error: Package ‘Affinity Photo 2’ in /nix/store/kxvw2dp30hgaks4pmwvsc06rx356y676-source/scripts.nix:52 has an unfree license (‘unfree’), refusing to evaluate.

       a) To temporarily allow unfree packages, you can use an environment variable
          for a single invocation of the nix tools.

            $ export NIXPKGS_ALLOW_UNFREE=1

          Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
                then pass `--impure` in order to allow use of environment variables.

       b) For `nixos-rebuild` you can set
         { nixpkgs.config.allowUnfree = true; }
       in configuration.nix to override this.

       Alternatively you can configure a predicate to allow specific packages:
         { nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
             "Affinity Photo 2"
           ];
         }

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
         { allowUnfree = true; }
       to ~/.config/nixpkgs/config.nix.
