Steps To Reproduce

nix-repl> :lf
...
other stuff, :?, etc
...
nix-repl> import <nixpkgs>
nix-repl> :ll

Expected behavior

no crash. only my 2nd time using nix repl, but I expected some info on the result of loading the flake and/or of importing Nixpkgs.

Additional context

Checklist

I did look at the other three "potential duplicates" and this does seem quite different. I now realize my version is not the latest, so I will update my nix and hope this has been fixed.

• checked latest Determinate Nix manual (source)
• checked open bug issues and pull requests for possible duplicates

3.18.1 is fairly old at this point (released on 23 April; we just released 3.21.5 today), could you try updating to a newer version and see if it happens again?
