Mqtt issues with new authentication method

After a recent home assistant update to 0.77.3, I get the following message on the main screen:

"
Invalid config
The following components and platforms could not be set up:

  • mqtt
  • binary_sensor.mqtt
  • sensor.mqtt
  • switch.mqtt
    Please check your config.
    "

And all my mqtt devices are not working anymore :frowning:

Can anyone help me?

Thanks
Daniel
