Please describe your issue in as much detail as possible:

I'm running steamlink on Ubuntu 24.04 (version 1.3.16.287, installed via flatpak). It correctly detects the workstation running steam and my game controller, but crashes quickly after pressing 'start to play'.

The crash is 100% reproducible.

The console log is as follow:

$ flatpak run com.valvesoftware.SteamLink
