      Description

      i tested on the same code, same flow, and same BT devices that tested with windows 10, seem QT BLE lib doesn't work well on Windows 11
      it also happened with the QT examples

      while connect to device and scan sevice information. i got a error message from QT:

      Could not await service operation (A method was called at an unexpected time.)

      or in paired mode:

      Could not obtain list of included services (The operation completed successfully.)

      Windows 11: beta. but i think it almost the same with  release version that will be release next month.

      Happened on both of paired and unpairing mode. nerver seen it work on upairing mode, it is better in paired devices.

      • Some time i connected to my device, read device information, enable data streaming.... but it likes a lucky. almost of time, it doesn't work.
        happened with normal devices
      • Crash: paired BT device, call discovering (start/stop discovering each 10s) -> a few times, it crashed
        happened with device has exception cases
      • Freeze: paired BT device, discovering run always run. turn device power off, turn it on -> freeze. (do few times). seem some things blocked while Update data for device.
        happened with device has exception cases
