Hi @rhand

If your ACF field Event Categories is a taxonomy and its set to return the Term Object (and you have Load and Save terms selected), replace:
$event_cat_ids = array( 37, 47 );
With:

$event_categories = get_field('event_categories');
$event_cat_ids = wp_list_pluck( $event_categories, 'term_id' );

So now looks like:

<?php
$event_categories = get_field('event_categories');
$event_cat_ids = wp_list_pluck( $event_categories, 'term_id' );

#$event_cat_ids = array( 1, 31 );

$args = array(
		'post_type' 		=> 'event',
		'post_status'		=> 'publish',
		'posts_per_page'	=> -1, // show all posts.
		'order'				=> 'DESC',
);
			
$args['tax_query'] = array(
	'relation' 		=> 'OR', 

	array(
		'taxonomy'	=> 'event_category',
		'field'		=> 'term_id',
		'terms'		=> $event_cat_ids
	),			
		
);

$query = new WP_Query( $args );
if( $query->have_posts() ) : 

	while( $query->have_posts() ): $query->the_post(); ?>
	<p><?php the_title(); ?></p>
	<?php endwhile;  wp_reset_postdata();

endif;
?>

I’ve tested this code and can confirm it works, returning the posts of the selected categories in your multi select
