问题的根本在于HashLocationStrategy的路由模式不兼容ActiveReportsJS Report Designer组件。解决这个问题的方法是使用PathLocationStrategy路由模式。下面是示例代码，展示如何在ASP.NET Boilerplate Angular应用中使用PathLocationStrategy：

1. 在app.module.ts文件中，将路径策略设置为PathLocationStrategy：

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';
import { HttpClientModule } from '@angular/common/http';
import { LocationStrategy, PathLocationStrategy } from '@angular/common';

@NgModule({
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    HttpClientModule,
    AppRoutingModule
  ],
  declarations: [
    AppComponent
  ],
  providers: [
    { provide: LocationStrategy, useClass: PathLocationStrategy }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {
}

2. 在ASP.NET Boilerplate的默认模板中，修改app.component.ts文件，禁用HashLocationStrategy：

import { Component, OnInit } from '@angular/core';
import { AppSessionService } from '@shared/common/session/app-session.service';
import { AppAuthService } from '@app/shared/common/auth/app-auth.service';
import { SignalRHelper } from '@shared/helpers/SignalRHelper';
import { ApplicationInfoDto, SessionServiceProxy } from '@shared/service-proxies/service-proxies';
import { Router } from '@angular/router';
import { TokenService } from '@abp/auth/token.service';
import { AppConsts } from '@shared/AppConsts';

@Component({
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.less']
})
export class AppComponent implements OnInit {

  private version: string;
  private releaseDate: string;
  isSessionExpired = false;

  constructor(
    public appSessionService: AppSessionService,
    public authService: AppAuthService,
    private _sessionService: SessionServiceProxy,
    private _router: Router,
    private _tokenService: TokenService
  ) {}
