Built-in Bluetooth not Working

[Shahyan_Abbas]

My HP Zbook 17 (I think G4) has built in Bluetooth i.e. Intel(R) Wireless Bluetooth(R) . I was using wireless earbuds with it like normal when all of a sudden they disconnected, and wont reconnect even after restarting the PC. I opened device manager to see the Bluetooth icon with an exclamation mark. In the properties it said, "windows has stopped this device because it has reported problems. (code 43)". I first disabled and re-enabled it, didn't work, then I uninstalled it (without checking the delete driver checkbox) and re installed it with the same driver as it was "the best driver available on this pc", this worked and my earbuds connected. but as I played the movie I was watching, within a minute it disconnected again with the same situation. This repeated a few times, and one thing I noticed was that whenever I uninstalled it and clicked on "scan for hardware changes", I would hear a faint squeak lasting less than a second (almost like when the DVD player reads a DVD)
I searched for a solution online. I ran the Bluetooth troubleshooter, which just reinstalled the driver, with the same results. I checked Windows Update and there were three updates:

But before these updates could download, I figured I should try other solutions because my Bluetooth was working fine a day ago, so update probably didn't have anything to do with it (I may be wrong though)
So I then disabled it from the device manager, opened the services app, changed the startup type of "Bluetooth Support Service" to automatic, and the enabled the Bluetooth from the device manager. This also didn't work, and the update was still downloading so I went on and uninstalled it from the device manager, this time I checked the "delete the driver" checkbox, figuring that when I re-install it then it would automatically search for drivers online, but this time it just said that no drivers were found (on this pc) and it didn't search online for the drivers.
Now, I'm stuck with the troubleshoot saying that my PC doesn't even have Bluetooth, I don't see the Bluetooth icon in the action center and the Built-in Bluetooth now shows up as an "Unknown Device" in the device manager, and I don't even have the original driver, or where I can find a new driver, or if the hardware is the problem (because of the squeaking, I don't remember if it made that noise before this issue too), or if I should've waited for the Windows update to complete.
Also, I just noticed that one of the updates (in the screenshot) failed to install, I don't know if this has anything to do with what I'm facing. I have no idea why I'm facing this issue randomly, or what I should do to fix it
I don't know much, but I tried to find drivers and I couldn't find any, or which driver I had before, or which driver I need to install, it's probably  Intel(R) Wireless Bluetooth(R) but I don't know the specific version.
