Any ideas?

Well, have a look at the breaking changes. In my case, the scenes messed the whole system up.
Without a word about it in the logs…

from scenes.yaml:

      media_player.Receiver:
        source: 'Chromecast'

to

      media_player.Receiver:
        state: on
        source: 'Chromecast'

My issue was the api_password entry in configuration.yaml

Can you tell me how you changed it to run in 0.101.x?

I commented it out with #. That feature isn’t supported any longer
