"Then go to the Dell Drivers website and search for the Qualcomm Wi-Fi and Bluetooth Driver. It will be under the "Network" category."

I'm not sure that's the best approach. The OP hasn't identified his Bluetooth provider. It could be Qualcomm or Intel, depending on which network option he selected at purchase. If it's the Killer AX1650/Intel option, I've found that the Intel Driver Support Assistant has more recent drivers than Dell Support Assist. I'm using driver version 22.10.0.2. The release notes show an issue that could be related to what the OP is seeing:

Unplug to drain the power worked for me...THANK YOU!!!!!!!

Strangely enough, this also worked for me, lol.

I did so many things... uninstalling the bluetooth drivers, resetting defaults in BIOS, turning off quick startup, and many other things I saw online. This is the one that did it. 

This has happened to me twice in the last two days.  The solution works, but we shouldn't have to go through this.

I noticed that I never had this problem until I started using the Alienware Mobile Connect app.  I'm going to go ahead and uninstall that and see if the problem continues.  If it disappears, I will know the Alienware Mobile Connect app (which was very unreliable and did not function as intended) was the problem.

So the solution was to drain flea power from the machine?

And the Blutooth worked after that?

Yup

I was on the phone with Dell support fir 3 days regarding this issue. They told me to reset my whole computer.

I did and nothing. Still had Bluetooth off. Scoured the internet, trying to type in the right phrase and ended up here. Tried it and voila. Works like a charm again. This is the second time this has happened to me.   

I almost punched a wall. 

Hello,

Thanks you, had the same issue.

My xbox one bluetooth controller was messing and disconnecting / reconnecting every 10 minutes, then sudently bluetooth stopped to work.

After unpluging powercable and drain power and putting back, it worked.
