GNOME broken

Alright so sorry for late answer, so I followed [HOW TO] Install KDE (plasma), GNOME, XFCE, Cinnamon, MATE, Budgie, LXQt, LXDE and UKUI Dekstop Environments this guide to install gnome lol, and now I think everything is working? Now I need to find the zorin gnome extensions since somehow all of them have dissapear but i think I can fix this with some patience before making a clean install
