Hide Custom Shipping When Multiple Items are in cart - woocommerce

Question

I added a plugin that creates a shipping method with Id "pisol_extended_flat_shipping:52540" when the product category is "baby-care" and the country is "India" and It's working fine. When someone adds different products from different categories in the cart and one of the categories is "baby-care". then I want to hide the "pisol_extended_flat_shipping:52540" shipping when there are other category products at the checkout along with "baby-care".
I tried this code, but not working
function check_cart_categories() {
$baby_care = false;
$other_categories = false;
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
$product = $cart_item['data'];
if ( has_term( 'baby-care', 'product_cat', $product->id ) ) {
$baby_care = true;
} else {
$other_categories = true;
}
}
return ( $baby_care && $other_categories );
}
add_filter( 'woocommerce_available_shipping_methods', 'hide_pisol_extended_flat_shipping' );
function hide_pisol_extended_flat_shipping( $available_methods ) {
if ( check_cart_categories() ) {
unset( $available_methods['pisol_extended_flat_shipping:52540'] );
}
return $available_methods;
}

Here is the full code:
function check_cart_categories() {
// your logic here...
}
add_filter( 'woocommerce_package_rates', 'hide_pisol_extended_flat_shipping' , 10, 2 );
function hide_pisol_extended_flat_shipping( $rates, $package ) {
if ( check_cart_categories() ) {
unset( $rates['pisol_extended_flat_shipping:52540'] );
}
return $rates;
}
If it doesn't work, try increasing the priority of the hook (I set default 10). Some plugins are also using this hook and could interfere.
