Angular7:CanLoad Auth guard挂起浏览器

我已经创建了一个AuthGuard服务并实现了它的CanLoad接口,如下所示

import { Injectable } from '@angular/core';
import { CanLoad, Router } from '@angular/router';

@Injectable({
  providedIn: 'root'
})
export class AuthGuard implements CanLoad {
  constructor(private router: Router) { }

  canLoad() {
    if (localStorage.getItem('isLoggedin')) {
      return true;
    }
    this.router.navigate(['/auth/login']);
    return false;
  }
}

下面是我的应用程序路由模块

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { AuthGuard } from './shared/guard/auth.guard';

const routes: Routes = [
  { path: '', loadChildren: './layout/layout.module#LayoutModule', canLoad: [AuthGuard] },
  { path: 'auth', loadChildren: './auth/auth.module#AuthModule' },
  { path: 'not-found', loadChildren: './not-found/not-found.module#NotFoundModule' },
  { path: '**', redirectTo: 'not-found' }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

当我检查“浏览器网络”选项卡时,没有下载任何文件,我看到一个空白的白色页面和

platform-browser.js:613 Throttling navigation to prevent the browser from hanging. See https://crbug.com/882238. Command line switch --disable-ipc-flooding-protection can be used to bypass the protection
