Angular2 app is not working on Microsoft edge

My angular2 application is not working on Microsoft edge, while it's working fine on chrome and firefox.

I looked at this question, but it didn't help me.

I am getting following error on the Edge console:

Below is package.json file:

import { Injectable } from '@angular/core';
import { Router, CanActivate, CanDeactivate, ActivatedRouteSnapshot, 
RouterStateSnapshot } from '@angular/router';
import { Observable } from 'rxjs/Observable';

@Injectable()
export class AuthGuard implements CanActivate, CanDeactivate<any> {

constructor(private router: Router) { }

canActivate(activeRoute: ActivatedRouteSnapshot, state: RouterStateSnapshot) 
 {
    if (localStorage.getItem('jwttoken')) {
        // logged in so return true
        return true;
    }
    // not logged in so redirect to login page
    this.router.navigate(['/login']);
    return false;
  }

canDeactivate(component: any): Observable<boolean> | boolean {
    localStorage.setItem('previousRoute', this.router.url);
    $('.zoomContainer').remove();
    return true;
 }
}

Any help would be highly appreciated.

Thanks in advance.

Finally figured out that the issue was with LocalStorage.

Something was wrong with the Microsoft edge, I ran following command in the PowerShell and the issue was resolved:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

In your app, there will be file polyfills.ts, there just uncomment the polyfills required for IE

/**
 * This file includes polyfills needed by Angular and is loaded before the app.
 * You can add your own extra polyfills to this file.
 *
 * This file is divided into 2 sections:
 *   1. Browser polyfills. These are applied before loading ZoneJS and are sorted by browsers.
 *   2. Application imports. Files imported after ZoneJS that should be loaded before your main
 *      file.
 *
 * The current setup is for so-called "evergreen" browsers; the last versions of browsers that
 * automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
 * Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.
 *
 * Learn more in https://angular.io/docs/ts/latest/guide/browser-support.html

Your Login guard must be using some Libraray of Javascript or Brower which your Microsoft Edge wont support (LocalStorage, Sessions etc), can you please post your login guard here.
