Do you get that problem if you boot with that dongle unattached?

well... looks like no

That dongle might be faulty. You could try using it on another PC.
In case it isn't the dongle's fault: you could check in pacman.log what you updated before it started happening. You could see what happens on linux-lts. You could try without NetworkManager.
