ytmusic tracks not playable

playing songs seems to be completely broken now.
recently i am getting the following error when i try to:

2024-05-30 16:10:59,999 INFO [78700:YTMusicBackend-13 (_actor_loop)] mopidy_ytmusic: YTMusic Found AUDIO_QUALITY_MEDIUM stream with 144054 bitrate for XXXXXXXXX

2024-05-30 16:11:00,114 WARNING [78700:Core-16 (_actor_loop)] mopidy.core.tracklist: Track is not playable: ytmusic:track:XXXXXXXXX

I confirm the issue; adding the same song as youtube:video:... circumvents the issue.
I can also confirm that adding a ytmusic:playlist:... works fine, i.e. its content is added to the track list as ytmusic:track:... items which, of course, don't play.
