Xlib.error.DisplayNameError: Bad display name ""

[Kev1n121]

But how? Is this also possible with a Raspberrypi? and with Jellyfin Tizen? When running flatpak run com.github.iwalton3.jellyfin-mpv-shim it gives me error : 2024-02-03 10:55:07,269 [ INFO] conf: Loaded settings from json: /home/ktkev/ .var/app/com.github.iwalton3.jellyfin-mpv-shim/config/jellyfin-mpv-shim/conf.jso n
