Playing Sonos radio favourites stopped working

Hi,
I’m experiencing issues with my sonos integration since a couple of days. I’m calling play_media or select_source with radio stations in my Sonos favourites, both is not working anymore - but used to work. I’m getting “UPnP Error 402 received: Invalid Args from ”. Calling a spotify playlist favoured in Sonos the same way works, so it seems to be related to the radio favourites. Does anyone have an idea?

Please post the full error text from the home-assistant.log
