The module throws the following error:
LogicException: Two #config_targets both target "message" in the "system.maintenance" config: `$form['maintenance_mode_message']` and `$form['maintenance_mode_message']['value']`
after updating to Drupal Core 10.2.x.
It is caused by Drupal Core 10.2.x using #config_target (see
https://www.drupal.org/project/drupal/issues/3382510
📌
Introduce a new #config_target Form API property to make it super simple to use validation constraints on simple config forms, and adopt it in several core config forms

and

), which doesn't seem to support #type text_format yet.
Update module to any Drupal Core 10.2.x version and visit the Maintenance mode page.
Remove usage of #config_target and keep using default config-functionality for the time being.
