The Bluetooth driver is giving you issues while updating it. I regret for the inconvenience. Our Intel® Driver Update Utility is having some issues so it is necessary to update the drivers manually.
I suggest you to do the following.
Update the BIOS to version 0034
Continue with the latest Chipset and Management Engine drivers
Chipset version: 10.1.1.14
Management Engine v 126.96.36.1996
Then, download and keep the latest wireless and Bluetooth drivers in your desktop.
Wireless Technology-Based Driver
Bluetooth® v 18.16.1
Go to device manager uninstall and delete the current Wireless and Bluetooth drivers, restart the system and install the new drivers from your desktop.
Let me know how it works.
