@jarvis Thanks for that. Did add the option to choose number of posts as well so adjusted the code and am now using:

/ Variables
$number_of_events = get_field( 'number_of_events' );
// print_r($number_of_events);
$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'	=> $number_of_events,
		'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(); ?>
	<?php the_title(); ?>

	<?php endwhile;  wp_reset_postdata();

endif;
?>

I see two times the one and only post for event category local.

This when I choose 1 event and category local. So somehow things repeat themselves. Two, I see a warning

Warning: foreach() argument must be of type array|object, null given in /Users/jasper/code/site/wp-includes/class-wp-list-util.php on line 164

and when I print print_r($event_cat_ids); I see

Array ( [0] => 180 )
Event Two Local

Array ( [0] => 180 )
Event Two Local

so closer, but not quite.
