Ionic4 fallback to the root page or angular fallback to the root page

in the project, you need to click the button to go back to the root page. Since both ionic4 and angualr are routed, if you jump directly, the router can still go back to the previous page. Did you send it back to the root page, which the router can"t jump back to?
