Estoy usando la última versión de CLI angular (16) e intento cargar rutas de carga lenta pero falla por alguna razón, no puedo encontrar ninguna pregunta o solución nueva para esto.

Estructura de la carpeta:

core.component.html:

<router-outlet></router-outlet>

core.component.ts:

import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {RouterModule} from '@angular/router';

// Modules
import {AdminAreaModule} from './+admin-area';

// Services
import {GlobalsService, RegexService, UtilsService} from './shared';

// Main app component
import {CoreComponent} from './core.component';

@NgModule({
  imports: [
    BrowserModule,

    // Feature modules
    AdminAreaModule
  ],
  exports: [
    BrowserModule
  ],
  declarations: [
    CoreComponent
  ],
  providers: [
    GlobalsService,
    RegexService,
    UtilsService
  ],
  bootstrap: [CoreComponent]
})
export class CoreModule {}

admin-area-router.module.ts:

import {NgModule} from '@angular/core';
import {RouterModule} from '@angular/router';

// Global modules
import {ComponentsModule, SharedModule} from '../../shared';

// Lazy loaded modules
import {AdminAreaModule} from '../admin-area.module';

@NgModule({
  imports: [
    RouterModule.forChild([
      {
        path: 'admin',
        loadChildren: 'app/+admin-area/admin-area.module#AdminAreaModule'
      }
    ])
  ],
  exports: [
    RouterModule
  ]
})
export class AdminAreaRouterModule {}

admin-area.module.ts:

import {NgModule} from '@angular/core';

import {AdminAreaRouterModule} from './router';

import {ComponentsModule, SharedModule} from '../shared';

@NgModule({
  imports: [
    ComponentsModule,
    SharedModule,

    // Feature modules
    AdminAreaRouterModule
  ],
  exports: [
    ComponentsModule,
    SharedModule,
    AdminAreaRouterModule
  ]
})

export class AdminAreaModule {}

Esto arroja un error:

Error in ./CoreComponent class CoreComponent - inline template:0:0 caused by: No provider for RouterOutletMap!

¿Por qué recibo este error cuando claramente tengo unrouter-outlet en micore.component.ts ¿archivo?
