add_filter( 'frm_restrict_options_for_logged_out_users', '__return_false' );

Use this code example if you want to revert to the previous functionality for a single field, where there is no filtering when not logged in.

add_filter('frm_restrict_options_for_logged_out_users', 'restrict_options_for_logged_out_users_field', 10, 2);
function restrict_options_for_logged_out_users_field( $restrict_options, $field ) {
	$target_field_id = 9594;
	if ( $target_field_id === (int) $field->id ) {
		$restrict_options = false;
	}
	return $restrict_options;
