I updated my TeamSpeak client to 3.5.0 Beta channel just a view minutes ago. After that the client crashed with a reference to qt5. After updating my qt version via brew to the version 5.14.0 the client works again.
I don't know if that is just a problem having a separate qt version installed or if that happens to others without, too.
OS version: Mac OS Catalina 10.15.2
