Bug in windows bluetooth le GetGattServicesAsync method

The problem description:
Sometimes it is not possible to get some response from the method GetGattServicesAsync with the parameter BluetoothCacheMode.Cached or BluetoothCacheMode.Uncached. Only the windows restart helps to reconnect the le device and to get the services from the le device.

We use Windows.Devices.Bluetooth.dll with .Net Framework 4.6.1 to build the class library.
The Windows PC shall connect the Bluetooth le device.

Steps for the problem reproducing:

1. Discovery the devices with the determined service
   
2. Call the method FromBluetoothAddressAsync with the Bluetooth address of LE device
   
3. BluetoothLEDevice is found
   
4. Pair the LE device with desktop:
   
   
5. Check the connection status. If the status connected, call the method GetGattServicesAsync(BluetoothCacheMode.Cached)
   
6. Sometimes is not possible to get the response from GetGattServicesAsync. After 30 seconds we cancel the task, dispone BluetoothLEDevice, unpair and try to reconnect le device. The reconnection is failed and only the Windows restart helps to establish the connection to the le device.

Bluetooth LE Enumerator is Missing

Sometimes, when i want to add my PS4 Controller to play Minecraft Windows 10 Edition, the "Wireless Controller" (DualShock 4) device doesn't appear despite enabling the "Pair" Function on the Controller (by holding SHARE + PS), i went to check the Device
Manager, and found out that "Microsoft Bluetooth LE Enumerator" is missing on the list, only "Microsoft Bluetooth Enumerator" appears.

The Bluetooth LE Enumerator is what works as the Device Detector, and i can't find a way to re-install it.
