The following reason prevents Simple Like Button from being uninstalled:

Problem/Motivation

I want to uninstall the module but get this message,

Simple Like Module
The following reason prevents Simple Like Button from being uninstalled:
There is content for the entity type: Simple Like. Remove simple like entities.

Remove simple like entities is linked such that it would reveal the entities with likes so one can remove d likes or something but clicking on the Remove simple like entities link shows this error,

Error: Call to a member function getFieldStorageDefinition() on null in Drupal\Core\Entity\ContentEntityBase->getEntityKey() (line 1310 of /home/skilttop/public_html/core/lib/Drupal/Core/Entity/ContentEntityBase.php).

Thus I am not able to uninstall the module.

I have Config Delete so I looked in available configurations on the site and couldn't find a mention of simple.like.button

Any ideas on how I can delete any configurations set by the module so I can uninstall it or perhaps any other way to do it.

Thanks.
