[CyberShadow]

It seems to be due to a bug in nixpkgs.

The bug manifests with the nixpkgs version in flake.lock, but not a more recent version.

Looks like it wasn't even intended as a bugfix.

If we can get that exact version to build, feel free to update the lock.

See #218

just increasing the max-call-depth by adding --option max-call-depth 1000000 to the nix build command solved it for me as a workaround
