This is an identical issue and “workaround” as this link:
I am having this issue on a 2022 Tesla Model Y with AMD CPU. When playing Arc on first connect of BT, there’s no info on the vehicle media player. I then started a song from Plexamp. I saw the Plexamp metadata. I stopped Plexamp and returned to Arc and pressed play and had proper Arc metadata. However there is no coverart displayed on the Tesla.
