I'm receiving an error with a path of Drupal\path_alias\AliasManager
Upgrading to Drupal 9, I was running a test to see which blocks and/or modules would fail. And there were plenty... like this AliasManager error
TypeError: Argument 4 passed to Drupal\{module}\Plugin\Block\{custom_block}Block::__construct() must be an instance of Drupal\Core\Path\AliasManager, instance of Drupal\path_alias\AliasManager given, called in /app/web/modules/custom/{module}/src/Plugin/Block/{custom_block}Block.php on line 103 in Drupal\{module}\Plugin\Block\{custom_block}Block->__construct() (line 82 of /app/web/modules/custom/{module}/src/Plugin/Block/{custom_block}Block.php)
The code this error came from is
/**
* Constructs a new {module}Block object.
*
* @param array $configuration
* A configuration array containing information about the plugin instance.
* @param string $plugin_id
* The plugin_id for the plugin instance.
* @param string $plugin_definition
* The plugin implementation definition.
* @param Drupal\Core\Path\AliasManager $path_alias_manager
* The path alias manager.
* @param \Drupal\Core\Path\PathMatcher $path_matcher
* The path matcher.
* @param \Symfony\Component\HttpFoundation\RequestStack $request_stack
* The request stack object.
* @param \Drupal\Core\Path\CurrentPathStack $path_current
* The current path stack.
* @param \Drupal\Core\Entity\EntityStorageInterface $header_images
* The header images entity storage.

*/
public function __construct(array $configuration, $plugin_id, $plugin_definition, AliasManager $path_alias_manager, PathMatcher $path_matcher, RequestStack $request_stack, CurrentPathStack $path_current, EntityStorageInterface $images) {
parent::__construct($configuration, $plugin_id, $plugin_definition);
$this->pathAliasManager = $path_alias_manager;
$this->pathMatcher = $path_matcher;
$this->requestStack = $request_stack;
$this->pathCurrent = $path_current;
$this->headerImages = $images;
}
/**
* {@inheritdoc}
*/
public static function create(ContainerInterface $container, array $configuration, $plugin_id, $plugin_definition) {
return new static(
$configuration,
$plugin_id,
$plugin_definition,
$container->get('path_alias.manager'),
$container->get('path.matcher'),
$container->get('request_stack'),
$container->get('path.current'),
$container->get('entity_type.manager')->getStorage('image')
);
}
The error was in using the old method to call the use and params.
Pre Drupal 9 method
use Drupal\Core\Path\AliasManager; @param Drupal\Core\Path\AliasManager $path_alias_manager
New Drupal 9 method
use Drupal\path_alias\AliasManager; @param Drupal\path_alias\AliasManager $path_alias_manager
