Did you already try the sensible thing and just looked up the error?
Did you try unsetting the environment variable SESSION_MANAGER?
What did you try?

But just saying, the flatpak is not officially built or supported by TeamSpeak.

Removing these folders:

/var/lib/flatpak/app/com.teamspeak.TeamSpeak/
/home/peterge/.var/app

does not work. Even reinstalling does not fix it. I do not find anything else online, just this, which just say removing ~/.ts3client fixed it. But in the flatpak installation its inside /var/lib/flatpak/app/com.teamspeak.TeamSpeak/
I did not unset SESSION_MANAGER yet.
I did nothing more yet, because last time it was fixed after 2 reboots.
