Uninstalling Gnome Maps also uninstalls many critical packages
Edit: This issue previously reported that Phosh was missing after a crash, on a new phone with little altered. It turns out that Phosh was actually uninstalled, along with many other packages, when I tried to uninstall Gnome Maps. This caused the crash, though delayed until the phone went to sleep. I then confused cause and effect
I was using the software app, but I'm assuming it's just a frontend to Pamac or Pacman itself. pacman.log, beginning from the moment i tried to uninstall Maps, through the moment I first discovered the problem.
Can't believe it took me this long to diagnose! Scary stuff.
