MC 33 Xamarin RFID application development

Currently I'am developing a (Xamarin Forms 4) application for the MC33, a part of the application is the reading and writing of (EPC Gen2) RFID tags.

When I want to debug my application I cannot scan RFID tags, I get an exception of 'Charging in Progress-Command Not allowed'. The full error is at the end of this post.

Things I've tried:
MC33 in docking station without power
MC33 binded to a USB charging cable

But both had no results, to continue my development I now use the TC20 Zebra terminal.
