XPS 15-9560, Bluetooth NOT working

Hi, I'm using XPS 15 9560 with Windows 10 Pro Build 17661 version and after the latest update Window10's Blutetooth Open/Close button started NOT Working.

as you can see below screenshots my bluetooth device seems ok, driver is already up to date but I'm not able to change the status of the win10's bluetooth option, it doesnt discover any bluetooth devices and not able to send/receive files to any device ( also unable to set visible my laptop on bluetooth )

I already updated all the BIOS, device drivers and windows updates but there is nothing change, could you please help me about solving this problem.
