ESPHome cannot update due to following error : 'loose object is corrupt'

I'm trying to update the ESPHome to the latest version in HA, but since version 2024.8.3 it is not working anymore

The log file shows the following message

INFO ESPHome 2024.8.3
INFO Reading configuration /config/esphome/athom-garage-door-9cecba.yaml...

The yaml file in ESPHome is as follows

substitutions:
  name: athom-garage-door-9cecba
packages:
  athom-garage-door: github://athom-tech/athom-configs/blob/main/athom-garage-door.yaml

esphome:
  name: ${name}
  name_add_mac_suffix: false
api:
  encryption:
    key: xxx


wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

Does anyone has idea or tip where i can find a solution? Thanks in advance.
