Shortcode blocking import

Please help because I don’t know what the connection is between WP All Import and the Snippets plugin. I want to update the stock from an external linked .csv file, so only ‘stock’ is what I want to update, which works fine until I activate a shortcode-containing PHP code in the Snippets plugin, for example:

‘add_shortcode( ‘myprice’, function(){
global $product;
return $product->get_price();
});’

I don’t know the connection between the two and why they conflict.

And please don’t tell me to turn off Snippets because I need both the Snippets code and the import. I don’t understand the connection between the two, and why WP All Import is being disrupted by an external snippet. In theory, it should only update the stock in WooCommerce.
