QtBluetooth is unable to connect a device under Windows 10

I'm migrating some code from Qt 6.2.2 to Qt 6.9.0.

I have some code uqing QtBluetooth, I could migrate the code under Android, Linux and even Raspberry (arm Linux).
Under Windows, my code compiles but crashs when trying to connect a device.

My code is hard to isolate, so I tested the example provided with Qt 'lowenergyscanner', it's unable to connect a device, the log reports:

qt.bluetooth.windows: HRESULT: 2147500036 /* await(service.GetCharacteristicsAsync(), earlyExit) */
qt.bluetooth.windows: Characteristic operation failed
qt.bluetooth.windows: Characteristic operation failed
qt.bluetooth.windows: Characteristic operation failed
qt.bluetooth.windows: Characteristic operation failed
qt.bluetooth.windows: Characteristic operation failed
qt.bluetooth.windows: Connect to device failed due to timeout!
Error: "Error occurred trying to connect to remote device."

Note that all othe platforms than Windows just work fine
Note that my code using 6.2.2 is able to connect the exact same device

Note that I'm running a Windows 10 machine. is Windows 11 required?
