Timeout reached when creating systray icon

[mauricioquintela]

No systray presents itself when running plex-mpv-shim, although the program works fine. According to console logs, a timeout is reached in pystray after roughly 20 seconds.

Running arch (6.1.44-lts) with up-to-date mpv and plex-mpv-shim, as well as pystray and tk. Error presents itself both in standard xfce and in i3+polybar.
