Hello. My name is Michael. I can help you with your question.
That's sufficient to try some things. The first thing I would do is restart the computer.
Then go back into bluetooth pairing - when you do this, as long as the other device is discoverable, you should see it on the list of devices to which you are able to connect
How about if we boot that puppy in safe mode?
To load your Mac in Safe Mode, press and hold the Shift key while it boots. You can stop holding the Shift key when you see an Apple logo and progress bar. To leave Safe Mode, just reboot your Mac without holding the Shift key
