I trying query posts by custom fields following example from this page:
https://www.advancedcustomfields.com/resources/query-posts-custom-fields/

I have an Custom Post type called “playlists”
I have a custom field (select options) called “categorias”
I have the selections options: Educação, Arte, Experimentação

I trying make a loop for display the results if the option selected is “Education”:

<?php 

// args
$args = array(
	'numberposts'	=> -1,
	'post_type'		=> 'playlists',
	'meta_key'		=> 'categorias',
	'meta_value'	=> 'Educação'
);

// query
$the_query = new WP_Query( $args );

?>
<?php if( $the_query->have_posts() ): ?>
	<ul>
	<?php while( $the_query->have_posts() ) : $the_query->the_post(); ?>
		<li>
			<a href="<?php the_permalink(); ?>">
				<img src="<?php the_field('event_thumbnail'); ?>" />
				<?php the_title(); ?>
			</a>
		</li>
	<?php endwhile; ?>
	</ul>
<?php endif; ?>

<?php wp_reset_query();	 // Restore global post data stomped by the_post(). ?>

But this not show anything
I don’t have the pro version.

A select field with multiple values stores those values as a serialized array in the database. To do a query on this type of field see section 3. Multiple custom field values (array based values) on this page https://www.advancedcustomfields.com/resources/query-posts-custom-fields/
