As I've done before, I shared this in the official Manjaro forums, but to be honest, perhaps a lack of team members, but support isn't what it used to be.

I’ve been trying to get a headset working that previously connected as headphones but not as mic, and along the way I ran a system update and something went wrong but I can’t find what that something is.

Right now if I try to connect to Bluetooth, I get the error br-connection-canceled and once I saw br-connection-unknown. Also tried pairing as a new device but it won’t detect anything in pairing mode.
Have tried different kernels (4.19.x, 5.4.x, and currently 5.14.x) and tons of troubleshooting from similar issues, but I don’t know where to go from here. Is it possible the update didn’t go properly, or maybe a bug in the update?

I don't know if this is something that can be nailed down, or if a fresh install is the way to go but any help will be very much appreciated!

Problem solved, and I don't know if this was a "correct" way to handle it, but I tried it and it worked. I rolled back using Timeshift to a backup from before the update and BT was working, so I then re-applied the updates using the terminal and it's still working. :D

That is why backing up your system is a good idea.

Exactly as @brickwizard shared. Not sure if the article gets into it, but to add to this I use a separate ssd for /home and am able to then restore or roll back system using Timeshift, or even change OS without much effort. That's another post perhaps. :)
