[Wayland] GPU error 8704 on app startup, unable to connect to dbus

[MEMESCOEP]

The problem

Github Desktop has stopped launching properly under Wayland (still works just fine with X11 on the same machine). No window appears but there is an icon on the taskbar (clicking the icon does nothing). When the app starts, I get the following errors in the console (in order):

• [2:1218/234944.495683:ERROR:bus.cc(407)] Failed to connect to the bus: Failed to connect to socket /run/dbus/system_bus_socket: No such file or directory
• LaunchProcess: failed to execvp: xdg-settings

• [2:1218/234356.689364:ERROR:gpu_process_host.cc(997)] GPU process exited unexpectedly: exit_code=8704

These errors are thrown three times before it gives up and hangs. These errors also persist after several restarts/reinstalls.

-- EDIT --
I forgot to mention in the original message that launching from the pinned taskbar icon results in the same issue. It's link is configured to run run --branch=stable --arch=x86_64 --command=start-github-desktop --file-forwarding io.github.shiftey.Desktop @@u %U @@.

Release version

Operating system

Steps to reproduce the behavior

1. Install via flatpak: flatpak install flathub io.github.shiftey.Desktop

2. Run Github Desktop in a terminal using either of the following commands: flatpak run io.github.shiftey.Desktop --enable-features=UseOzonePlatform --ozone-platform=wayland --enable-wayland-ime, flatpak run io.github.shiftey.Desktop

3. Restart the computer

4. Observe the error

Additional context

I haven't had this problem with any other Electron applications, even discord (mostly) works just fine. I'm thinking a recent Kubuntu update may have broken something. I've tried it on another computer that is also running the same OS, and the problem persists (both systems are up-to-date and had linux installed around the same time).
