I'm getting a lot of really frustrating error messages - I can only guess it's a frontend issue because most things are still functioning ok in the background but a lot of bits of the webserver aren't working as they should. The only error message in the logs is:
2025-12-29 13:49:04.105 ERROR (MainThread) [music_assistant.webserver] Error handling message: config/players: 'provider'
Usually accompanied by "🚫 provider" red popup. I get the message when clicking settings > providers and settings > players, but none of the providers themselves are showing any errors. The Players page shows no players, and the homepage was previously not listing any of the home-screen stuff (although that seems to be working now). I can go through artists/albums, I can search, and I can play music correctly and I can access the player settings pages from the player bar and that works fine.
My HA integration is also reporting errors, which are clearly related, looking at the error messages:
Traceback (most recent call last):

I'm on 2.8.0b3, using Sendspin, Squeezelite, Jellyfin, BBC Sounds and Tidal providers. I've tried disabling/enabling providers, restarting MA, restarting the whole server, no change.
