Critical Error After Multisite

Hi,

I am receiving a critical error when fetching orders, after updating WordPress to a multisite. Orders are not syncing anymore, can you please let me know if the plugin works with a multisite? Thanks. Here is the error:

?PHP Fatal error: ?Uncaught TypeError: current(): Argument #1 ($array) must be of type array, bool given in /home/customer/www/example.com/public_html/wp-content/plugins/xps-ship-integration/xpsship-integration.php:1133
