Get block programmatically It is possible get parent entity block by entity block_content? I don't know the block's machine name but I have a uuid of block_content
Use BlockContent::getInstances

$blocks = $block_content-&gt;getInstances();


or the code of this method directly:

$blocks = \Drupal::entityTypeManager()-&gt;getStorage('block')-&gt;loadByProperties([
  'plugin' =&gt; 'block_content:' . $uuid,
]);
