    Description

      Since macOS 12 connection attempts to Bluetooth devices lead to an app crash. It's working fine with macOS 11.x.
      xCode versions: 12, 13

      The problem can be reproduced as follows:
      1.) Open the lowenergyscanner example shipped with Qt.
      2.) Replace the pro file with the one attached here.
      3.) Put the MacInfo.plist into the project dir.
      4.) Compile and sign the app.
      5.) Run the app.
      6.) Connect to some Bluetooth device (I tested iPhone, Watch, and a GoPro camera). Everything works fine.
      7.) Run the app again. Now the app crashes everytime when trying to connect to a device.

      Here is the crash dump:
