Fatal error on config schema validation

Problem/Motivation

Hi,

I am currently opening a D11 branch for https://www.drupal.org/project/sobki_profile_bootstrap → .

On a fresh install, when executing Config Inspector, I obtain the following fatal error:

Symfony\Component\Validator\Exception\LogicException: The LangcodeRequiredIfTranslatableValues constraint is applied to 'core.entity_view_display.block_content.layout.default::entity_view_mode_restriction_per_role'. This constraint can only operate on the root object being validated. in Drupal\Core\Config\Plugin\Validation\Constraint\LangcodeRequiredIfTranslatableValuesConstraintValidator->validate() (line 27 of core/lib/Drupal/Core/Config/Plugin/Validation/Constraint/LangcodeRequiredIfTranslatableValuesConstraintValidator.php).

The config in question:

langcode: en
status: true
dependencies:
  config:
    - block_content.type.layout
    - field.field.block_content.layout.layout_builder__layout
  module:
    - layout_builder
    - layout_builder_restrictions
third_party_settings:
  layout_builder:
    enabled: true
    allow_custom: true
  layout_builder_restrictions:
    allowed_block_categories: {  }
    entity_view_mode_restriction:
      allowed_layouts: {  }
      denylisted_blocks: {  }
      allowlisted_blocks: {  }
      restricted_categories: {  }
    entity_view_mode_restriction_per_role:
      layout_restriction: all
      allowed_layouts:
        layout_onecol:
          content_editor: '0'
          webmaster: '0'
          site_builder: '0'
          administrator: '0'
...
      override_defaults: false
id: block_content.layout.default
targetEntityType: block_content
bundle: layout
mode: default
content: {  }
hidden:
  langcode: true
  layout_builder__layout: true

I think I will have the same error on other config with entity_view_mode_restriction_per_role, it is just the first one found alphabetically.

I have not found anything in layout_builder_restrictions_by_role or layout_builder_restrictions that will attach such validation so I guess with D11 upgrade some automatic config schema validation had been added by Core but at the wrong level. I don't know if Core issue or layout_builder_restrictions_by_role issue.
