Don't bother with guix refresh, it's meant for huix devs. If you have a previous generation of your profile, you could try and switch to it (guix package --roll-back), but you said that didn't work. You can also switch manually by repeating the steps Guix would take behind the scenes, manually.
You'll notice that ~/.guix-profile is a symlink to /var/guix/profiles/per-user/tyler/guix-profile. It itself is a symlink to the current generation, a file such as guix-profile-17-link. Change that last symlink to point to the previous generation instead, such as guix-profile-16-link. That's all you need to switch generation. Hopefully, that generation's manifest is not corrupted.
