bluetooth app does not connect using windows and mac

If Qt's example btchat example is used to test bluetooth connection between mac and windows, it always ends up giving error.

If you run btchat example on windows machine and also on Mac (macOS 13.0) when you try to connect (hitting connect button)from mac it always ends up with following error.

qt.bluetooth.darwin: IOBluetooth works only on the main thread or a thread with a running CFRunLoop
qt.bluetooth.darwin: IOKit error code: 1
qt.bluetooth.darwin: Manually interrupting IOBluetoothDeviceInquiry

This problem continues even with following

qputenv("QT_EVENT_DISPATCHER_CORE_FOUNDATION", "1");
