This looks like a nixpkgs issue given the path /nix/store/kp6kwb86xmzslskpwviq0z8wbcr9xssk-ladybird-0-unstable-2024-06-08.

There's known problems building from master on nixOS or in a nix environment (#371).

In theory the fonts should be quite findable in a standard nix environment, with the current fontconfig related patches. Can you redirect this issue to nixpkgs instead?

[ADKaster]

Since you're using ladybird-0-unstable-2024-06-08 and ladybird-0-unstable-2024-07-11 has just been released, I'm going to close this. Please try again using the latest nixpkgs version and report the font-related issues to the nixpkgs maintainer. If it seems to them like it's a problem in the code or build steps in our repo they can report it back to us.

As with any other package, if it doesn't work and there is a NixOS option you should try enabling it. Enabling programs.ladybird.enable should fix your issue.

And like @ADKaster wrote, please report any issue with the NixOS package in the nixpkgs tracker first. NixOS maintainers don't necessarily follow this tracker.

It should be enough to just set this in your configuration.nix:

fonts.fontDir.enable = true;

That's what programs.ladybird.enable does under the hood, yes
