How the problem can be solved?

$ nix-info --markdown 
 - system: `"x86_64-linux"`
 - host os: `Linux 6.6.45, NixOS, 24.05 (Uakari), 24.05.3844.a731b45590a5`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.18.5`
 - channels(root): `"nixos-24.05"`
 - nixpkgs: `/nix/var/nix/profiles/per-user/root/channels/nixos`

The problem disappeared setting correct system.stateVersion = "24.5". It was still 23.11.

system.stateVersion should never be changed.

Thanks for pointing that out.
When should I change system.stateVersion?
