Woocommerce – Warning: preg_match(): Compilation failed: quantifier does not follow a repeatable item at offset 1 in wp-includes/class-wp.php on line 222

Any pages with page type posts, order type posts, or posts show this error. This is only visible on a hosted environment. I cannot replicate the errors locally

I have done the following in this order:

1. deactivated all plugins
2. went to settings->permalinks and resaved the %postname% option
3. verified that error is still present with no plugins and permalinks reset.
4. Updated all plugins and themes.
5. Verified error is still present.
6. Followed the same procedure locally, and was not able to replicate this problem.

from class-wp.php:

foreach ( (array) $rewrite as $match => $query ) {
    // If the requested file is the anchor of the match, prepend it to the path info.
    if ( ! empty( $requested_file ) && strpos( $match, $requested_file ) === 0 && $requested_file != $requested_path ) {
        $request_match = $requested_file . '/' . $requested_path;
    }

    if ( preg_match( "#^$match#", $request_match, $matches ) ||
        preg_match( "#^$match#", urldecode( $request_match ), $matches ) ) {

        if ( $wp_rewrite->use_verbose_page_rules && preg_match( '/pagename=$matches[([0-9]+)]/', $query, $varmatch ) ) {
            // This is a verbose page match, let's check to be sure about it.
            $page = get_page_by_path( $matches[ $varmatch[1] ] );
            if ( ! $page ) {
                continue;
            }

            $post_status_obj = get_post_status_object( $page->post_status );
            if ( ! $post_status_obj->public && ! $post_status_obj->protected
                && ! $post_status_obj->private && $post_status_obj->exclude_from_search ) {
                continue;
            }
        }

        // Got a match.
        $this->matched_rule = $match;
        break;
    }
}

I have scoured the interweb for an answer on this, but I have come up with nothing. Let the WordPress Junkies speak please.
