I am getting a PDO error which seems related to the Media module After Drupal 8.8 upgrade media module is not working. 
In admin media links are not working e.g /admin/content/media
Error : 
The website encountered an unexpected error. Please try again later.


  Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'media' doesn't exist: SELECT COUNT(*) AS expression FROM (SELECT 1 AS expression FROM {media} base_table GROUP BY base_table.vid, base_table.mid) subquery; Array ( ) in Drupal\media\MediaListBuilder->getEntityIds() (line 158 of core/modules/media/src/MediaListBuilder.php).
