QGC V4.1.0 Won't start on Windows 8 machine


I’ve been using QGC V4.0.11 no problems, but just installed V4.1.0 and it won’t start. Starting the app just sits and consumes processor but nothing else happens. I tried starting from command prompt using:

qgroundcontrol --logging:full

This doesn’t even get to the console so I cant see any debug or logging info. Also tried the safe graphics mode version but same happens.

Anyone else have this issue?
