      We faced crashes during the discovering process when we shut down the BLE device (it is not paired!) meanwhile. This happend on multiple machines. It seems that the crash happens during the service discovery in the QLowEnergyControllerPrivateWinRTNew::connectToDevice method.

       

      I attached some pics of the callstack and the codelines.

       

      Would be great if anybody has a hint on that or look into it. I checked the bugreports and found this quite similar one: https://bugreports.qt.io/browse/QTBUG-70162. Not sure though if it could be connected.

       

      Env: Visual Studio 2017 on Win10 x64
