implode issue

Hi @aya.y, I'm trying to replicate this issue with the 8.2.2 version of this module in a Drupal 10.4 setup but the issue is not replicated.
Can you please mention the module version and the Drupal core versions, that will be helpful for replicating this issue and solve accordingly.

Thank you for your replay , this issue happens after i used composer update and i used the older version 8.x-2.1 and it has configuration already added.

• Drupal Version is 10.4.0
• Database Version 10.5.17-12-MariaDB-enterprise-log
• PHP Version 8.2.22
• anonymous_login 8.x-2.2

I can confirm the issue, with drupal 10.4.1 and php 8.3.15

It happens only on Anonymous login 8.x-2.2, reverting to drupal/anonymous_login:2.1.0 solves the issue

We only have one path, so our `anonymous_login.settings.yml` (as exported on anonymous_login:2.1.0, but not changed when updated to 2.2.0) is:

_core:
  default_config_hash: xyz
langcode: de
paths: /somepath/
login_path: /user/login
message: 'A nice message.'

But when I manually change to

paths: 
  - /somepath/
login_path: /user/login

then the issue disappears.

So i guess it's somethin about the config-schema, which does not change to a sequence when coming from an older version, perhaps only on Drupal 10, perhaps only when having a single entry (like me) or a config with windows-style-line-endings (like aya.y)

My workaround: changing the config-file to a sequence

I guess its related to #3495893, which occurs under the same circumstances (2.2.0, but not 2.1.0, paths-config in single line instead of list) and is triggered on the same object.
