[BUG] Discord tray icon stopped working after sytem update

[r7eyes]

Describe the bug The Discord tray icon stopped showing on my system after a system update, while others still work. I mainly use the Discord flatpak, but I tried installing the discord AUR package, as well as the Webcord flatpak, and all of them have the same issue.

journalctl shows an error as follows:

To Reproduce Steps to reproduce the behavior:

1. Launch Discord.

Expected behavior All system tray icons should work.

Screenshots N/A

Desktop (please complete the following information):

• Arch Linux 6.3.1-arch1-1
• sway version 1.8.1
• nwg-panel version 0.9.2

Additional context My suspicions is that it might have something to do with Arch updating to Python 3.11 from 3.10, where AUR packages that depends on Python break, and which before that the Discord tray icon still worked. I've rebuilt all my AUR packages that use Python (including python-dasbus) and all other system tray icons work from what I've tested so far, so I'm not sure why Discord specifically is having problems.
