Flatpak on Manjaro Add-On Startup Failed?

[SarahSzabo]

I'm on Manjaro KDE (2023-12-07 latest updates), and my Anki Killstreaks add on fails to start, which is a shame as I need FSRS at this point and really want this add on as it is amazing :)

The flatpak version is:

root@MidnightStarSign:/home/sarah# flatpak list | grep Anki
Anki    net.ankiweb.Anki        23.10.1 stable  system

I can provide any required information if required.
