First we have to get the list of blocks with block id which we can we get if we execute this query
<?php
$ids = \Drupal::entityQuery('block')->execute();
?>

If the block we created is not in this list(in the case of creation of custom block not assigned to any regiom)
, we have to place the block in some region and disable it.

<?php
$block = \Drupal\block\Entity\Block::load($block_id);
