Can't remove Poll Entities

Hi,

I can't seem to use Polls anymore. There setup to use them as an Entity Reference with another node type. The field on that node type was removed. Checking the poll overview results in WSOD:

TypeError: Argument 1 passed to Drupal\Core\Entity\Sql\DefaultTableMapping::requiresDedicatedTableStorage() must implement interface Drupal\Core\Field\FieldStorageDefinitionInterface, null given, called in /home/dkvision/staging/dorsoo.be/core/lib/Drupal/Core/Entity/Sql/DefaultTableMapping.php on line 331 in Drupal\Core\Entity\Sql\DefaultTableMapping->requiresDedicatedTableStorage() (line 512 of core/lib/Drupal/Core/Entity/Sql/DefaultTableMapping.php).

Trying to reinstall the module fails, because there are still entities. However, following the link to delete these entities results in WSOD as well.

Error: Call to a member function getType() on null in Drupal\Core\Entity\ContentEntityStorageBase->cleanIds() (line 998 of core/lib/Drupal/Core/Entity/ContentEntityStorageBase.php).

EDIT:

This one appears as well.

Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'db_dorsood8.poll__field_poll_node_reference' doesn't exist: SELECT 1 AS expression FROM {poll__field_poll_node_reference} t WHERE field_poll_node_reference_target_id IS NOT NULL LIMIT 1 OFFSET 0; Array ( ) in Drupal\Core\Entity\Sql\SqlContentEntityStorage->countFieldData() (line 1808 of core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

Any ideas how to get this to work? Thanks!
