I think it is realted to this part of your config:

    screensaver:
      entities:
        - entity:

try

    screensaver:
      entities:
        - entity: delete

instead if you want to have that empty.

(Even though error handling should be improved here.)

Yeah, that was it! :-)

Thanks a bunch for spotting that!
