1. 2.x src/Config/LanguageHierarchyConfigFactoryOverride.php \Drupal\language_hierarchy\Config\LanguageHierarchyConfigFactoryOverride::getFallbackChainFromConfigEntities()

Compute the fallback chain for a language code.

The entity type manager and language configuration entities should be available by the time this is needed, as language overrides are loaded during the Kernel request event. We cannot inject the entity type manager as a dependency because that would create a circular dependency.
