Can´t find my Username

[JustGruetze]

Hello, if i search my Channel name, and click connect, it gives me an "Error". It doesnt crash, only the Error. Even after i restarted my PC.

I installed the App Version v1.0.3 RC 2. The Standalone Option. I also installed the Runtime.et files. I marked them in a screenshot

Have a great Day, Thanks.
