Config manually builds a lot of packages after updating flakes

After updating my flakes my config manually builds a lot of packages.
Two of these packages fail building, Kitty and FFmpeg. FFmpeg fails a test, and Kitty has warnings as errors turned on.

Could one of my caches have changed keys? I use Hyprland, nix-community and chaotic-nyx caches.

here is my config: GitHub - KneeCapStealer/NixOSconfig
