Confirming what others have discovered:
It appears that the EQ settings provide some type of data to CarPlay when it attempts to utilize audio, but it crashes if it can’t find that data or it’s potentially corrupted.
Even if you don’t have the music app installed, like I did because my go-to is Spotify, it’s still providing some type of data that CarPlay needs. I reinstalled Music, went to EQ in Settings > Music and activated the EQ. Plugged in, crashed, unplugged, disabled EQ, plugged in, and now it’s functional with no issues.
Whatever data CarPlay needs exists within this setting, and it should function as a workaround until Apple fixes the bug.
Hope this helps!
