Thank you so much for your help, bcworkz.

Unfortunately that didn’t work. Even if I remove all my arguments from the wp_dropdown_users function, it still results in indefinite page loading. My code now:

function ls_authors_dropdown($output) {

	$welders = get_users( array(
		'role' => 'welder',
		'fields' => 'ID'
	));

	$welders_comma_separated = implode(",", $welders);

	$args = array(
		'include' => $welders_comma_separated,
	);

	$output = wp_dropdown_users($args);

	return $output;

}

add_filter( 'wp_dropdown_users', 'ls_authors_dropdown');

That fixed it! Thank you so much.

Same problem here. Titles & Metas is missing, other than the navigation bar at the top (General – Home – Post Types etc.)

Has anyone figured this out yet?
