Inserting anything always results in "terminated by signal SIGSEGV"

[Nintron27]

After updating my home-manager channel (in nix), every single time I try to insert anything into any document Helix crashes with the following error:

fish: Job 1, 'hx .config/nixpkgs/' terminated by signal SIGSEGV (Address boundary error)

The helix log shows this:

#7896 (comment)

The nix-unstable pkg is broken there is a PR to back port the patch to nixpkgs but it hasn't landed there yet. On nix you can use the official flake instead

[Nintron27]

Ah yup, I see. Thank you!

Backport has been merged: NixOS/nixpkgs#249163 (seems to not have been backported to the 23.05 release of nixpkgs but I think that's fine because that should build with an older version of rust)
