The crash report doesn’t show anything useful.
But where it does crash may be related to audio devices.
We are aware that virtual audio devices will crash the client.
Such virtual audio devices could be installed through Philips Hue Sync etc.
Does latest TS3 Client 3.6.0 also crash on start?
There you might get another crashdump in that case.
Should be stored under Library/Application Support/TeamSpeak 3/crashdumps
