Roon states metadata halted software update needed but when I go to Settings-About it shows current updates were installed and stable and there is a small circle circling endlessly by the search button that never stops.
I would reboot the core machine for a start, if still an issue open a new post under #support and fill in all the details you can
the rotating icon indicates either importing or music analysis is happening … check under library settings or clicking on the rotating icon
