Unable to access / while trying to open the project

I have encountered a strange bug - Whenever I close and reopen my project in Webstorm IDE and then launch the project, I receive a "cannot get" error. This issue is resolved if I delete the route {path: '', component: AppComponent}, and then the application works correctly. However, when I save, close, and reopen the project again, the same error reappears. But this time, if I add back the previously deleted route {path: '', component: AppComponent} to the routes, the project functions without any errors. It seems like I am caught in a cycle where I need to constantly adjust the routes every time I open my project. Any assistance would be greatly appreciated.

One issue that arises with Angular is that it may initially display errors, but upon recompiling after any file change, it uses cached data making the issue appear resolved. While the documentation may not explicitly mention this behavior, my years of experience have shown that Angular tends to work in this manner.

However, the compiler still retains the issue as evident from the console output, even though the browser can be opened without displaying any errors.

In relation to the "AppComponent" in the path, @Yuriy correctly points out that AppComponent does not need to be included in the Routes. The AppComponent serves as the static "Root Component", and the listed routes are rendered in the

<router-outlet></router-outlet>
placed anywhere within the app. Since the Appcomponent contains this RouterOutlet, there is no need to display the AppComponent within it. For more information on Routing, refer to Angular's Guide on the topic.

Please share your console output for additional insight (potential recursion or non-unique outlet).
