Performance issue on Block type admin page

Please review.

The attached patches do not work, actually. I already tried this approach and it still didn't work. What works for me in fact is switching the route provider permission handler, as in my updated proposed resolution.

/**
 * Implements hook_entity_type_alter().
 */
function my_module_entity_type_alter(array &$entity_types) {
  /** @var \Drupal\Core\Entity\EntityTypeInterface[] $entity_types */
  if (!empty($entity_types['block_content_type'])) {
    $entity_type = $entity_types['block_content_type'];
    $route_providers = $entity_type->getRouteProviderClasses();
    $route_providers['permissions'] = 'Drupal\user\Entity\EntityPermissionsRouteProvider';
    $entity_type->setHandlerClass('route_provider', $route_providers);
  }
}

Created a patch for removing the link. Please review.

I don't think just removing the link/functionality is the solution.

@yivanov what version is your site on? Have you updated to 10.1 yet?
There were some changes to the permissions wonder if that helps or hurts.

I am on 9.5 currently, but I see that the 10.1 version is actually using the permission handler that I suggested.

https://git.drupalcode.org/project/drupal/-/blob/10.1.x/core/modules/blo...

I guess that solves it in future releases, so no need to do anything else here. I couldn't find existing issue with that particular problem, so hopefully this one will help if someone is wondering.

If this not the issue that fixed it please correct me.
