Loading of images and plugin settings broken in 2.8.1@flatpak when not in dev mode

✅Resolved

Bazzite linux, plasma, Opendeck 2.8.1@flatpak
Opendeck does not load images or plugin settings any more, enabling development mode via settings fixes the problem.
Nothing in logs. Would be happy about learning how to debug loading of plugins while not in dev mode to provide more info.
