I have updated Drupal 9.0.1 to 9.2.2 via Composer. After updating, I am getting a fatal error.

Fatal error: Cannot redeclare Drupal\views\Routing\ViewPageController::getTitle() in /var/www/html/docroot/core/modules/views/src/Routing/ViewPageController.php on line 98

drush updb outputs the following.
