Steps to reproduce

Visit a taxonomy term page and got this error above. Debug this code from "single_content_sync\src\Form\ContentExportForm.php" on line 249 found out value $entity = 'taxonomy_term' (string not an object)

  public function access() {
    $parameters = $this->getRouteMatch()->getParameters();
    $entity = $parameters->getIterator()->current();
    $hasAccess = $this->contentSyncHelper->access($entity);
    return $hasAccess ? AccessResult::allowed() : AccessResult::forbidden();
  }

Drupal version: 9.4.1
PHP: 7.4.3
Single content sync version: 1.3.4

Proposed resolution

Add condition to handle if $entity is not Object from interface Drupal\Core\Entity\EntityInterface
