plugin causing fatal error on WP 6.3

To the plugin author:
The current version of this plugin (1.7.0.6?) causes a fatal error on line 251. We’ve temporarily fixed it on a site by deleting that line and adding this code

if (is_array($countries)) { $key = array_search($country_slug, array_column($countries, ‘Slug’)); } else { // Handle the situation when $countries is null or not an array. // You may want to log an error or throw an exception. error_log(‘Warning: $countries is not an array.’); }

Let me know when you have an official fix, thanks!
