After the installation of unityhub AUR package, all it was needed was a lib installation via:
sudo pacman -Syu gconf
Now i encountered another bad problem, i cant load my assets in the package manager. Every other built-in package is working out of the box. I cant provide any console log because it is opened by unityhub.
It is now working. Hilariously i simply reinstalled the unity hub AUR in a fresh installation of manjaro e voila. Working pretty well so far(tested only URP).
