Hi, I am unable to start the plex app on Ubuntu 24.04. I’ve tried both the snap and flatpak versions, it’s the same thing each time : the app just doesn’t start, and there isn’t even any error in the syslog.
I’ve tried to open a session under X11, but the result is the same : the app does not start, it only shows up for a few seconds in the process list before exiting. No window is ever shown. Nothing appears in the terminal after issuing the flatpak run command, it exits silently with code 0.
The only difference compared to wayland is that the syslog contains sometthing :

but nothing looks like an error, just some display info
