Razer Seiren V2 is loading forever in Synapse 3

Hey,

I got my new Razer Seiren V2 Pro today and i got big Issues with Razer Synapse.

1. Since i plugged in the Seiren V2 Pro my synapse is reacting very slow
2. When i click on Streaming the options of my mic are loading for ever. After 15min its still loading

I tired several USB Ports on my Asus Hero XII Mainboard and i reinstalled Synapse. 

Anyone knows how to solve it?
