Windows 10: Bluetooth audio devices causes laptop to bluescreen and restart

All of a sudden, playing audio out of a Bluetooth audio device headphones, speakers would cause my laptop to bluescreen and restart.Recently, when turning on my laptop, it would automatically connect to my Bluetooth speaker and then bluescreen. It would do this repeatedly. But when i turned off the Bluetooth speaker so that it couldn't connect to the laptop, it stopped bluescreening. My drivers are up to date. I have no idea what caused this issue to happen, or how to resolve it.Please help.

Cannot connect to Bluetooth audio devices (only) under 21H1.

I had no problem connecting Bluetooth audio devices while running Windows version 20H2, and had 3 different audio devices paired and working normally. Upon upgrading to the latest Windows 10 version (21H1, 19043.1348), they can no longer connect. There's nothing wrong with the devices. My 2nd system is running 20H2 and is connecting fine with them. On my primary system running 21H1, I go to the Bluetooth settings screen, see my paired devices in the list. I turn on a Bluetooth audio device... and nothing happens. Previously the laptop would auto-detect the audio device and I'd be good to go. So I select the paired audio device in the list, see the option button to "CONNECT" and press it. IMMEDIATELY, I'm given this message: "That didn't work. Make sure your bluetooth device is discoverable." It's obvious it's not even trying. It's an instant response. On my 20H2 laptop, when I try to manually connect to a Bluetooth audio device that's not turned on, it takes about 20 seconds or so until the "didn't work" message to appear. It's clearly trying. NOTE: I have a mouse device connected via Bluetooth and it's working perfectly fine. It's only audio devices that fail. Another vexing related issue -- if I try to remove any of my Bluetooth audio devices from the paired list, I get a "Remove Failed" message and nothing happens. Troubleshooting: Went to Devices --> Bluetooth. Did a View of hidden devices... and yes, there were duplicates of these devices listed. I deleted all of them. I rebooted and while they are absent from the Devices list, they're still showing up in the Bluetooth interface and behaving as before. I ran the Bluetooth troubleshooter that claimed to find a problem and fixed it, but rebooting showed that not to be the case. Either something appears to be wrong with 21H1, or I have some screwy configuration conflict going on.. I've got Realtek Bluetooth hardware. I have uninstalled Bluetooth and reinstalled the Realtek drivers. No help. Upgrading to 21H1 was long and tedious--I don't want to roll back to 20H2. Is there anything I can try to fix this? Thanks!

Bluetooth device shows "Code 39" error in Device Manager on Windows 10 laptop

I'm encountering an issue with my Bluetooth device on my Windows 10 laptop. In Device Manager, the Bluetooth device is displaying an error message: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)".

Here are some additional details about the problem:

• My laptop model is HP R007tx, and it is Bluetooth-capable.
  
• Despite the Bluetooth hardware being present, the device manager shows this error, indicating a problem with the device driver.
  
• When attempting to troubleshoot, I found that the Bluetooth driver's digital signature cannot be verified, suggesting a revoked signing certificate.
  

I've already tried the following troubleshooting steps without success:

• Reinstalling Bluetooth drivers obtained from the HP support website.
  
• Updating Windows and checking for driver updates.
  
• Restarting the laptop multiple times.
  
• Checking for dependencies and performing a System File Checker scan.
  

Despite these efforts, the error persists, and I'm unable to use Bluetooth functionality on my laptop.

Can anyone provide guidance on how to resolve the "Code 39" error with the Bluetooth device driver? Is there a way to address the issue with the driver's digital signature or any other troubleshooting steps I can try?

Your assistance would be greatly appreciated. Thank you!

Laptop details:

• Make and model: HP R007tx
  
• Operating system: Windows 10
  
• Bluetooth device error: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
