Subject: [PATCH] Fix: Ensure route.children existence before accessing in
 initRouter()

In the initRouter() function, added a check to ensure the existence of route.children before accessing it. This prevents the "TypeError: Cannot read properties of undefined" error that occurred when trying to access route.children[0] without confirming its existence. The check ensures that route.children is present and not an empty array before proceeding to access its elements.
