      Description

      this task is continuing from task: https://bugreports.qt.io/browse/QTBUG-96057 and https://bugreports.qt.io/browse/QTBUG-97578

      OS: Windows 10. and more often on Windows 11.

      When: random. but often on steps connect/disconnect/scan device info.

      Big issue: sometime, crash happened while device connected already and streaming data.

      Case 1:

      Case 2:

      ~QWinRTLowEnergyConnectionHandler()
          {
              qCDebug(QT_BT_WINRT) << __FUNCTION__;
              // To close the COM library gracefully, each successful call to
              // CoInitialize, including those that return S_FALSE, must be balanced
              // by a corresponding call to CoUninitialize.
              if (mInitialized == S_OK || mInitialized == S_FALSE)
                  CoUninitialize();
          }
      

      seem, it crashed after call: CoUninitialize().
