That white screen means there is probably a syntax error in your code. When working on PHP code you should enable wp debugging https://codex.wordpress.org/WP_DEBUG

Also I notices that there is an error in what I posted

<?php

$categories = get_field('my_category_field');
// make sure it is an array, if only one is
// selected it may return a single value
if (!is_array($categories)) {
  $categories = array($categories);
}
$tags = get_field('my_tags_field');
if (!is_array($tags)) {
  $tags = array($tags);
}
$args = array(
  'post_type' => 'post',
  'posts_per_page' => -1,
  'tax_query' => array(
    'relation' => 'OR',
    array(
      'taxonomy' => 'category',
      'terms' => $categories
    ),
    array(
      'taxonomy' => 'post_tag',
      'terms' => $tags
    )
  )
);
$query = new WP_Query($args);

// loop reuslts here to display posts

?>
