[Flatpak] Crash when opening audio / hotkey / whisper settings

Hey there,
I’m working on updating the TeamSpeak 6 Flatpak from beta2 to beta3, and I’ve run into a problem that only happens in the Flatpak version.

WIP: Update teamspeak to 6.0.0-beta3

I've tested it and it works generally, although the title bar is being shown two… times, I'm not sure if there is any env or start var to make the kde titlebar disappear. <img width="1920" height="78" alt="grafik" src="https://github.com/user-attachments/assets/a8c98623-015e-487e-ab66-7372acfb1d05" /> **EDIT**: There seems to be a crash issue when opening audio / hotkey or whisper settings, which does not appear on the default client. Until resolved, I'd suggest waiting to merge, help is appreciated https://community.teamspeak.com/t/flatpak-crash-when-opening-audio-hotkey-whisper-settings/62424

The client crashes instantly when you try to open the Audio, Hotkey, or Whisper settings. This doesn’t happen with the non-Flatpak version of the beta3 client.

I know the Flatpak version isn’t officially supported, but it’s already been downloaded over 129,000 times from Flathub. Flatpak is a really common way for Linux users to get their apps these days, so it would be awesome if you could consider supporting it officially, as an additional way to download the client on linux, as competitors are also providing official flatpak builds.

Thanks for looking into this! Let me know if you need any more info.
