Delete Spec Table bind to a product got “Fatal error” PHP 8.0.x on admin

Hi,

I use:
PHP 8.0.x
WordPress 5.9.1
WooCommerce 6.2

I got a “Fatal error: Uncaught TypeError” on edit a product:

Fatal error: Uncaught TypeError: sizeof(): Argument #1 ($value) must be of type Countable|array, string given in /home/domain.com/public_html/wp-content/plugins/product-specifications/inc/admin/views/product-load-table.php:18

There has been a critical error on this website. Please check your site admin email inbox for instructions.

Reproduce error:
– Create a Specification Table (With Group, Attributes): “X” table
– Create a Product “P” Product”
– Choice Specification Table: “X” Table
– Delete “X” Table
– Edit “P” Product
=> Got error on the edit product admin

=> Hot fix:

On: /wp-content/plugins/product-specifications/inc/admin/views/product-load-table.php:13

Change: => $groups = empty(get_post_meta($table_id, ‘_groups’, true))? [] : get_post_meta($table_id, ‘_groups’, true);

Please check.
Thanks
