Electron 15 has been [unsupported for some time now][1]. Unfortunately, electron 15 also has a [critical bug][2], which causes it to crash immediately when trying to render natively under wayland. This change upgrades the electron dependency to version 19, which is supported, and has fixed the bug.

I compiled the desktop app with electron 19 and played around with it a little, and I did not experience any strange behavior.
