Ah, the hazards of dd. The disk destroyer has been earned legitimately many times. I did it to myself once because I got cocky and failed to treat it with the proper fear and respect.
I use NixOS and I borked Gnome cusors by having Hyprland installed also. Not everything can be rollbacked but you can easily reinstall NixOS on a USB if you have to which is what I'm doing right now.
