PluginNotFoundException entity type does not exist when trying to uninstall any module

Question

I've got this drupal website from a client that the another developer created, and they've made a mess with many things in this site. I'm having a problem where every time I try to uninstall a module, this error appears:

Drupal\Component\Plugin\Exception\PluginNotFoundException: The "block_content" entity type does not exist. in Drupal\Core\Entity\EntityTypeManager->getDefinition() (line 150 of core\lib\Drupal\Core\Entity\EntityTypeManager.php).

Apparently there was a module "block_content" installed before. This module is uninstalled. So I've tried removing anything that could be causing this problem. So far I've tried:

removing the module from core.extension:

$moduleData = \Drupal::config('core.extension')->get('module');
unset($moduleData[$module]);
\Drupal::configFactory()->getEditable('core.extension')->set('module', $moduleData)->save();

This config was detected, and it was removed, but still this problem continues.

removed the module from system.schema:

$systemSchema = \Drupal::keyValue('system.schema');
$systemSchema->delete($module);

Also this config was detected, and it was removed, but still having the problem.

when trying to get the entity_type...

\Drupal::entityDefinitionUpdateManager()->getEntityType($entity_type)

The return is null; off course because the entity type does not exist and its not found.

So, what can I do to solve this issue? Can you point me to the right direction? It seems there is still a config pointing to this entity type, and drupal is not finding it.

Edit

I've added the full error message when trying to uninstall the redirect module:

I've also reverted the database to a version before my tries, and when running the code $entityType = $entityUpdateManager->getEntityType($entity_type); it finds "block_content", but when trying to run this command $entityUpdateManager->uninstallEntityType($entityType); it shows an error caught in the try catch (I've omitted the directories):
