Not entirely sure if it's a combination of MusicAssistant recently installed or not, however I noticed this morning when attempting to browse media on the Kodi entity that I get an 'unknown error' consistently.
I installed MusicAssistant on a physically separate machine in Docker container and have only added 1 of the 3 media_players i have configured in HA to it. When attempting to browse media on the kodi integration's media player, I am presented with an error [attached image].
I am also receiving the same with the other media_player entities.
I haven't removed either integration at the time of this writing as I am thinking this may not be an issue with either integration.
SS of HA version information attached.
