Cannot control lights anymore, cards are just displaying the first line


all over sudden I cannot control lights via dashboards and settings anymore besides turning them off and on or selecting existing scenes.

My lights are controlled either via zigbee2mqtt, zwave-js-ui or hue. As all of these are affected, it seems to be HA itself, which is having the issue.
I am running Home Assistant 2023.9.2 Frontend 20230911.0 - latest

  • tried Google Chrome 117.0.5938.92
  • tried Mozilla Firefox 117.0.1
  • restarted HA several times


Any help would be much appreciated :innocent:

Have you Card Mod installed? I recently read about similar problems.
