WP Cron errors & meta.json causing issues & errors with oiur website

Hi

We are getting errors when using your plugin where when some products are added to the Cart, which then causes an error in the backend, and the product doesn’t get added to the cart at all, but causes the shipping to display instead. I’ve been liaising with the hosting people and they say it is an issue /error with your plugin. I need to rectify this issue urgently.

Have latest wordpress 6.9.4 and have version 3.6.0 of your plugin installed latest. All plugins in backend are up to date.

Error is referring to Cache Cookie and meta.json for Meta for Woocommerce.

The POST /wp-cron.php 500 errors and the GET /meta.json 404s are coming from cron events and external requests (Facebook crawler). This indicates the issue is likely tied to the Facebook for WooCommerce plugin or its interaction with your theme/plugins.
