Error: 404 Product not found - when not logged in

-- HikaShop version -- : 6.4.0
-- Joomla version -- : 5.4.4
-- Error-message(debug-mod must be tuned on) -- : 404 Product not found

Hi,
Opening a link to a product from search engine

-When not logged in: Error 404 Product not found
-When logged in: The page displays normally

Instead of Error 404, ideally, i would like to display a logging / create account page

Thank you in advance for your feedback on this.
