I just updated my external boot drive to 14.5 yesterday (on a 2018 Mac Mini).
I have an old Apple [formerly internal] DVD/CD drive repurposed into an external enclosure:
View attachment 2378404
I just booted up the 2018 to 14.5.
Connected the old DVD/CD drive.
Put into it a home-burned audio CD.
The icon for the CD mounted on the desktop.
I opened the icon and right-clicked on the first track, and selected to open it with Quicktime Player.
The music plays.
It's not 14.5 -- your problem may lie somewhere else.
Try this:
Is that "Music" you're using in the window above?
If so, QUIT IT (or if it's iTunes, quit it as well).
Do you see the icon representing the music CD on the desktop?
Open it.
Do you now see the icons representing the audio tracks on the CD?
RIGHT CLICK (or CONTROL-click) on one of them and KEEP HOLDING DOWN the mouse button.
You should see a contextual menu of the various apps that might be able to open the track.
Try EACH ONE and see what happens.
