I was yesterday recommend to use something similar:

'tax_query' => [
        'taxonomy'         => 'event_category',
        'include_children' => false,
        'field'            => 'name',
        'terms'            => block_value('event-category')->name,
    ], 

So to work with ACF fields I would then use

<?php
/**
 * Events CPT Block
 *
**/

// Create id attribute allowing for custom "anchor" value.
$id = 'pm-' . $block['id'];
if( !empty($block['anchor']) ) {
	$id = $block['anchor'];
}

// Create class attribute allowing for custom "className" and "align" values.
$className = 'block-pm';
if( !empty($block['className']) ) {
	$className .= ' ' . $block['className'];
}
if( !empty($block['align']) ) {
	$className .= ' align' . $block['align'];
}

// Variables
$number_of_events = get_field( 'number_of_events' );
// print_r($number_of_events);
$event_object = get_field_object('events_category');
// print_r($event_object);
$event_cat_name = $event_object['value'];
$event_cat_slug = $event_cat_name[0]->slug;
// print_r($event_cat_slug);

$args = array(
    'post_type' => 'event',
    'posts_per_page' => $number_of_events,
    // 'event_category' => $event_cat_slug
    'tax_query' => [
        'taxonomy'         => 'event_category',
        'include_children' => false,
        'field'            => 'name',
        'terms'            => $event_cat_slug, // 
    ], 
);
$the_query = new WP_Query( $args ); ?>

<?php if ( $the_query->have_posts() ) : ?>

    <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
        <h2><?php the_title(); ?></h2>
    <?php endwhile; ?>

    <?php wp_reset_postdata(); ?>

<?php endif; ?>

not sure yet how to get term ids loaded from the events_category field. So far I have only been able to get arrays:

print_r($event_cat_name);
Array ( [0] => WP_Term Object ( [term_id] => 179 [name] => Virtual [slug] => virtual [term_group] => 0 [term_taxonomy_id] => 179 [taxonomy] => event_category [description] => [parent] => 0 [count] => 3 [filter] => raw [meta] => Array ( ) ) [1] => WP_Term Object ( [term_id] => 180 [name] => Local [slug] => local [term_group] => 0 [term_taxonomy_id] => 180 [taxonomy] => event_category [description] => [parent] => 0 [count] => 1 [filter] => raw [meta] => Array ( ) ) )

or the first slug of slugs given by chosen event categories:

print_r($event_cat_slug);
virtual

I can switch from term object to term id. But still, how to load the term ids chosen in a variable I can add to terms in the tax_query? Any suggestions?
