After I had an issue with my display which forced me to manually turn off my computer, I couldn't open gnome-software. It does nothing when I click on the icon and when I try opening with "gnome-software" in the terminal, all that returns is 21:03:48:815 Gdk Error 71 (Protocol error) dispatching to Wayland display.
I found another thread that said to switch from Wayland to X, but I'm running an external GPU (3070) that only displays video when I'm in Wayland.
