[Resolved] Multicurrency not working when enabled PHP for hiding prices for visitors

I have this simple PHP code running which hides prices for visitors (not logged in users):

add_filter( 'woocommerce_get_price_html', 'bbloomer_hide_price_addcart_not_logged_in', 9999, 2 );

function bbloomer_hide_price_addcart_not_logged_in( $price, $product ) {
if ( ! is_user_logged_in() ) {

$price = ' <div>' . __( 'Cena po zalogowaniu', 'bbloomer' ) . '</div>' ;
remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart', 10 );
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );
add_filter( 'woocommerce_is_purchasable', '__return_false' );
}
return $price;
}

After enabling, multi currency stops working: &wcmlc=USD gets added to the URL, but the price does not change. I have also tried with Woocommerce Wholesale Prices plugin, to see if the error was at my end, but the result was the same. Need solution to this problem.
