Why can't Bluetooth headphones connect to PC?

Question

Bluetooth

Hello! The laptop does not have a built-in Bluetooth module, so I bought the simplest usb module. Everything worked ok, but the quality was lame (not surprising with a module for 100r). So I wanted to change the driver. Changed it and it's all gone. I removed the firewood and reinstalled everything through Windows updates. After that, the earpiece does not connect, it just stands "paired". I click connect, it says unable to connect. The phone is connected and the files are transferred. The earpiece is connected to the phone and everything is ok.
How can this be solved (without buying a new module)?

Answer 1

Winda!!! Apparently there is something glitched and not removed. Either look for it, or reinstall Windows if you need it urgently.

Answer 2

I'll try reinstalling drivers or windows
