I think this thread goes really wrong here. We should go back to basics and understand what the problem here is. Pamac is a graphical program, but also can be used as a terminal program to update your system and also install additional software thru flatpak and snaps plus the AUR.
The best thing is to turn all those 3rd party options in settings off and try to do a system update. @zuluugugulumugu you can simply open a terminal window and issue pamac update and post the result. Also checking your /var/log/pacman.log file will give you a clue which updates were done on the OS side of things. Snaps and Flatpaks are separate systems of how you can install software. The AUR may interfere with regular OS updates.
Posting the output of inxi -Fazy will give a general idea of your system.
