Hi! I have a somewhat similar issue, Zorin OS and bluetooth worked for a while and then one day I started the computer and none of my bluetooth devices were connected.
When I tried activate bluetooth, the tab was inactive like I had no bluetooth hardware.
However I have bluetooth with my motherboard which worked with Windows 11 and then Zorin 17 and 18. See specs here: https://pg.asrock.com/mb/AMD/B650E%20PG-ITX%20WiFi/
Any idea what may have caused bluetooth to not be recognized anymore, and what I should do to reactivate it?
Thanks!
