The website encountered an unexpected error. Please try again later.
Drupal\Core\Config\ImmutableConfigException: Can not set values on immutable configuration file_entity.settings:max_filesize. Use \Drupal\Core\Config\ConfigFactoryInterface::getEditable() to retrieve a mutable configuration object in Drupal\Core\Config\ImmutableConfig->set() (line 32 of core/lib/Drupal/Core/Config/ImmutableConfig.php).

I tested your patch and it looks all good, I'm using in production since a fre days now w/o any issue.

I added to the patch also a fix for the #element_validate which needs to be an array.
