Windows 10: Driver for Bluetooth Hands-free Audio: This device cannot start. Code 10 {Access Denied}

Using Windows Home 10. Version 10.0.19043 Build 19043. Dell XPS 15 about 6 years old. The error message continued: "A process has requested access to an object, but has not been granted those access rights." I did uninstall and install. Checked the driver. Downloaded a version of the driver from Broadcom and restarted. Same problem.I found this out as I started using a Sennheiser Bluetooth earphone. I have to remove and connect again to get it to work, which is cumbersome. I am assuming that the above problem is causing this, but am unsure.

Bluetooth issues (Code 43 on the bluetooth driver, and code 10 (access denied) on the hands-free audio driver)

I did those steps numerous of times and I got the code 43 fixed and the code 10 (access denied) for the Hands-Free audio still exist and I still cannot connect my Xbox One S controller to it, even with my USB Bluetooth device by ASUS. The one in my ASUS
X54C works without issues. Thanks for the tip. I also notice I don't see the Bluetooth Hands-Free service in the services applet.

Scratch that: it's giving me that error code again. I also did the steps on that site and it's still giving me issues.

Here's the message I get when I try to pair my controller:





And my phone:

 

Audio Service not starting - access denied

My audio service is refusing to start regardless of what I try on Windows 10 1803.

I have attempted the following:

• Re-installing audio drivers
• Updating audio drivers
• A full virus scan
• A disk check
• An SFC check
• Making sure all the dependencies of the Windows Audio Service are running

None of these have succeeded in changing anything.
Whenever I try to start the audio service, I get this error message:




This made me think it is potentially the firewall messing everything up, so I start up Windows Defender and get this error message:




Are these two problems related, and does anyone know how I can fix it?

EDIT:
The Windows Defender Antivirus Service and Windows Defender Antivirus Network Inspection Service are both not running, and when I try to start them I get this error:




I imagine that this is connected in some way but I have no clue how to fix it.

 

Bluetooth issues (Code 43 on the bluetooth driver, and code 10 (access denied) on the hands-free audio driver)

I recently purchased an ASUS PCE-AC55BT network card that has both Wireless AC 1200 (Intel Dual Band Wireless-AC 8260) and Bluetooth 4.2 (Intel Wireless Bluetooth(R)) that requires an open USB 2.0 header on the motherboard. After I installed the card and
its drivers, everything was working, for the most part. And after I restart the computer or attempt to pair my Xbox One S controller via Bluetooth to my desktop, everything goes south. The Bluetooth driver throws a code 43: Windows has stopped this device
because it has reported problems (Code 43). The only way to get the Xbox One S controller to connect is by the Micro USB cable.

Specs:

The picture above is the Bluetooth Hands-Free Audio driver that's throwing the code error along with the access denied error. How does one go about fixing the code error 10 message? I also did the following with the diagnostics:

1) Re-installed the Bluetooth adapter drivers

2) Ran SFC /SCANNOW in Command Prompt (nothing found)

3) Ran the troubleshooting in both the Bluetooth portion and hardware & devices under the find and fix other problems category to no avail**

4) Re-seated the card and the Bluetooth cable that's required to no avail

5) Updated the drivers to the latest one to no avail

If I run the Bluetooth troubleshooting, I get the code 43 on the card itself.
