Error - ContactPageAccess::access" requires a value for the "$user" argument

Strange thing, I just ran into this message on a Drupal 10.1 page.
It's also a further tab on the user profile page (for Homebox 3.0.x).

I also found #2883266: RuntimeException: Callable "Drupal\contact\Access\ContactPageAccess::access" requires a value for the "$user" argument. in Drupal\Component\Utility\ArgumentsResolver->handleUnresolvedArgument() → :
But no view and no usage of contact module (which is just enabled by default on the vanilla DDEV installation).

This is the implementation I'm using:

/**
 * Implements hook_local_tasks_alter().
 *
 * @throws \Drupal\Component\Plugin\Exception\InvalidPluginDefinitionException
 * @throws \Drupal\Component\Plugin\Exception\PluginNotFoundException
 */
function homebox_local_tasks_alter(&$local_tasks) {
  // Add route to display on the user profile page.
  $homeboxTypeStorage = \Drupal::entityTypeManager()->getStorage('homebox_type');
  $homeboxTypes = $homeboxTypeStorage->loadMultiple();
  $userId = \Drupal::currentUser()->id();
  /** @var \Drupal\homebox\Entity\HomeboxTypeInterface $homeboxType */
  foreach ($homeboxTypes as $homeboxType) {
    if ($homeboxType->getUserTabEnabled()) {
      $local_tasks['homebox.user_profile.homebox_type.' . $homeboxType->id()] = [
        'id' => 'homebox.user_profile.homebox_type.' . $homeboxType->id(),
        'title' => $homeboxType->label(),
        'route_name' => 'homebox.user_tab',
        'base_route' => 'entity.user.canonical',
        'weight' => -100,
        'route_parameters' => [
          'homebox_type' => $homeboxType->id(),
          'owner' => $userId,
        ],
        'class' => '\Drupal\Core\Menu\LocalTaskDefault',
        'provider' => 'homebox',
        'options' => [],
      ];
    }
  }
}

Perhaps it helps someone to find the root cause. For now I'll just remove the old contact module ;)
