    Hi, look like I wasn't the only one who faced this, but my problem is now fixed. Here is the process I followed.

    1. Go to device manage and under bus serial unistall "Device Descriptor Request Failed" in yellow, and shut down your pc or laptop. In my case, I shut down the laptop.
    2. Hold and press the power button for 60 sec. After that i restarted my laptop and the problem was fixed.

    1

    Open the Settings App (gear icon on your Start Menu)

    Go to System - Troubleshoot

    Click 'Other Troubleshooters'

    Run the Bluetooth troubleshooter from the resulting page

    Check if Bluetooth is then working

    2

    If not, open Device Manager (accessible by right clicking your Start Button)

    At the top of Device Manager, choose View - Show Hidden Devices

    Does that show hidden Bluetooth device(s)

    if so, right click and uninstall that

    Restart your PC

    Check if Bluetooth is then working

    3

    If Bluetooth is still not working, go to the support page for your PC on the manufacturers website, then from there, download and install the Bluetooth device drivers they recommend.

    I am also having the same issue, I updated my machine and it deleted my bluetooth, I can no longer see it in device manager and cannot run the troubleshoot either as it give me an error and sends me to a microsoft page.

    I tried to roll back the update but no luck and I even went as far as to reset my full machine and still no luck.

    Is there any update on a fix for this as I use my PC for work and can no longer connect my headset etc..

    If Bluetooth is not showing or working after the Windows 11 security update (KB5074109), there are a few steps you can take to troubleshoot the issue:

    1. Check Bluetooth Settings: Ensure that the Bluetooth radio is turned on. You can do this by going to Settings > Devices > Bluetooth & other devices and checking if Bluetooth is enabled.
    2. Restart Bluetooth Services: Sometimes, restarting the Bluetooth services can help. You can do this by opening the Run dialog (Windows + R), typing services.msc, and looking for Bluetooth-related services to restart.
    3. Update Bluetooth Drivers: It's important to ensure that your Bluetooth drivers are up to date. You can check for updates through Device Manager or visit your hardware manufacturer's website for the latest drivers.
    4. Check for Windows Updates: Sometimes, additional updates may be released to address issues caused by previous updates. Go to Settings > Windows Update and check for any pending updates.
    5. Reinstall Bluetooth Device: In Device Manager, you can uninstall the Bluetooth device and then restart your computer. Windows should automatically reinstall the driver.
    6. Check for Compatibility Issues: If the issue persists, it may be related to compatibility with the new update. You can check if there are known issues with the specific update affecting Bluetooth functionality.

    If none of these steps resolve the issue, you may want to consider rolling back the update or seeking further assistance from Microsoft support.
