Seems the new i3wm fish.config need
sudo pacman -Syu --overwrite '*'
Change from neofetch to garuda
## Run fastfetch if session is interactive
if status --is-interactive && type -q fastfetch
fastfetch --load-config garuda
end
About the conflict, I must revert the config.fish from i3wm
If you like the new style, use in terminal
sed -i 's/--load-config neofetch/--load-config garuda/g' ~/.config/fish/config.fish
