Welcome to the Zorin Forum. Always nice to meet new users. Have you checked this thread? https://forum.zorin.com/t/bluetooth-fails-to-connect-to-headphones/24624
I posted a link to a page that explains how to install pipewire, it solved all my issues connecting to Bluetooth speakers and headphones a while ago. In case it's your main pc, you should give it a try on a zorin image before you commit on it. Just to be on safe side and avoid destroying anything.
