Problems with Airplay in Pipewire

A while back I made the happy discovery that Airplay support is baked into Pipewire.

A simple

pactl load-module module-raop-discover

And suddenly my homepod mini was available as a sink. However at some point over the months pipewire started adding bogus instances

They all look identical, but clicking on any but the “correct” one will kill my gnome session and kick me back to GDM.

Any suggestions on a fix/workaround? Or way to diagnose in more detail. My knowledge of Pipewire is pretty minimal as normally It Just Works.
