Connect with bonding fails

Description

I've been trying to make a BT connection to a BLE device which uses "just works" to connect.
But when trying to bond to the device i'm getting a pop-up on the bottom right corner from windows. With the text "click to add a device". When clicking on this pop-up mt BT settings will open and a seperate pop-up wille open with "unknown device", "bonding failed".

What I Did

This is the code i use at the moment.

    async def scan_for_devices(self, timeout=5.0):
        """Scan for available BLE devices and return a list of device names and MAC addresses."""
        devices = await BleakScanner.discover(timeout=timeout)
        return [(device.name, device.address) for device in devices if device.name]

    async def connect_to_device(self, mac_address):
        """Connect to the selected device by its MAC address."""
        self.client = BleakClient(mac_address)
        try:
            await self.client.connect()
            self.connected_device = mac_address
            print(f"Connected to {mac_address}")
            return True
        except Exception as e:
            print(f"Failed to connect to {mac_address}: {e}")
            return False

One of my findings where that this issue is only on windows. MacOS has no trouble with the pairing/bonding using this code.

Also i found out this issue does not occur when bonding has already been done before using another app e.g. "Bluetooth LE Explorer"

Logs

orignial:

Let me know if i can add any extra information if needed.

Thanks in advance.
