Bluedevil says adaptors not found

My laptop had Manjaro xfce and hyprland until yesterday 20th may 2024. Bluetooth worked fabulously.
Shifting to endeavour now shows that bluetooth adapters are not found.

Probably relevant logs:

I am dual booting and bluetooth never worked on windows, but that’s a gaming part only so I never cared about bluetooth there.

Not being in the best state of mid will reference you to here

As a sidenote have seen a few people over the last day or so post about BT issues, have you tried using a different kernel?

changing to LTS kernel solved the problem

Nice that you could solve this, when the next update comes out maybe try the mainline kernel again and if it don’t work as you know now you can easily select the LTS one (this is what I stick to as there have been shutdown/reboot issues on my sysytem in the past)
