Unhandled JavaScript Errors 1. Unhandled JavaScript Errors: An uncaught JavaScript error during component initialization or data loading after returning can cause the page to stop rendering or functioning. 2. Check the Router Configuration: Make sure the route you're returning to is properly defined in your routing file (app-routing.module.ts or similar) and that the path exactly matches the expected URL. 3. Inspect Route Parameters: If the route uses parameters, check how they are handled upon return.
