Odd that your previous function didn’t work..

I tried thinking outside of what you’ve done so far and perhaps this would work? It’d be a lot simpler altho maybe not as good performance-wise.. I don’t think it matters tho since it’s in the admin and it’s not that big off a loss that anyone would notice.

function my_acf_save_post( $post_id )
{

	//The fields have already been saved to the database so lets retrieve them
	$event_start = get_field('field_5217ac66687dc', $post_id);
	$event_end = get_field('field_524b4ca5ff418', $post_id);
	
	//check if event_end exists, if it was empty it should not. You can make sure of this in database.. perhaps it has to be changed to $event_end == ''
	if(!$event_end){
		//update event_end. Parameters are field key of event_end, event_start value and the post id. 
		update_field('field_524b4ca5ff418', $event_start, $post_id);
	}
	
}
 
// run AFTER ACF saves the $_POST['fields'] data to database
add_action('acf/save_post', 'my_acf_save_post', 20);
