Bluetooth device connected but not showing up in Output Device

In order to remove another audio device from my Mac, I deleted the HAL folder from Library/Audio/Plug-Ins/ (This is the advice I got from a quick google search, I don't understand the mechanics of it at all) It removed the device I wanted to remove but now my Galaxy buds are not working. They connect to the bluetooth successfully for a few seconds and then disconnect automatically. Even when they are connected, the headphones do not show up in the list of Output devices. If someone has any solutions, please help me out.
