The issue is likely with the new Bluetooth adapter I have installed. My Bose headset fails with this error(although my AirPods connected just fine):
bluedevil-wizard[6183]: kf.bluezqt: PendingCall Error: "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."
My phone also fails but with the error:
kf.bluezqt: PendingCall Error: "Authentication Canceled"
