Problem with inserted code, what wasn’t before

I’m having problem with inserted code, that wasn’t causing an error before

This is the code:

// Edit WooCommerce dropdown menu item of shop page//
// Options: menu_order, popularity, rating, date, price, price-desc
 
function my_woocommerce_catalog_orderby( $orderby ) {
    unset($orderby["price"]);
    unset($orderby["price-desc"]);
    return $orderby;
}
add_filter( "woocommerce_catalog_orderby", "my_woocommerce_catalog_orderby", 20 );

It should remove sort by price from Woocommerce listing options.

When I hover over the dropdown menu, at the top right on my site, it glitches.
