The result of get_post_meta might be null or anything else, you can cast the result to array to solve the issue.

function larus_user_review_print_review_badge($post_id, $echo = true) {

    $rating_type = 'number';
    $rating_criteria = get_post_meta( $post_id, 'user_review' . 'rating_criteria', true );
    $rating_criteria_count =  count((array)$rating_criteria); //<-cast to array
    
    $output = '';
    $score_array = array();
