javascript - No capturado (en promesa): ChunkLoadError: Cargando fragmento ... " solo con Firefox (Angular 9.1.2)

No entiendo por qué mi aplicación no funciona en Firefox pero sí funciona en Chrome.

Eliminar loadChildren con import() funciona...

import {NgModule} from '@angular/core';
import {RouterModule, Routes} from '@angular/router';
import {LayoutComponent} from './layout/layout.component';

const appRoutes: Routes = [
  {
    path: '', component: LayoutComponent,
    children: [
      {path: '', redirectTo: 'components', pathMatch: 'full'},
      {
        path: 'components',
        loadChildren: () => import('./pages/component-creator/component-creator.module').then(m => m.ComponentCreatorModule)
      },
      {
        path: 'templates',
        loadChildren: () => import('./pages/template-creator/template-creator.module').then(m => m.TemplateCreatorModule)
      },
    ]
  },

  // Not found
  {path: '**', redirectTo: 'components'},

];

@NgModule({
  imports: [RouterModule.forRoot(appRoutes, {
    enableTracing: false, // tracing for debug
    onSameUrlNavigation: 'reload',
  })],
  exports: [RouterModule]
})
export class AppRoutingModule {
}

¿Alguna idea?

¡Gracias!
