    This Filter does the following:
    -Attaches to WooCommerce Add to Cart Validation: Uses the woocommerce_add_to_cart_validation filter to validate the add-to-cart process.
    -Checks Quantity Being Added: If the quantity is more than one, it displays an error message and prevents the addition.
    -Iterates Through Cart Items: Loops through each item in the cart.
    -Checks for Product or Variation in Cart: If the product or its variation is already in the cart, it displays an error message and prevents adding the same product again.
    -Returns the Validation Result: Returns true if the product can be added (i.e., not in the cart and quantity is one) or false if the conditions are not met.
    -Replace 'domain' with your theme's text domain for proper internationalization of the error messages. This code ensures that the site doesn't hang when a product is added to the cart and that only one quantity of each product is allowed. If you still encounter issues after implementing this solution, it might be related to other aspects of your WooCommerce setup or conflicts with themes/plugins, and further investigation would be required.
