Angular 如何修复此错误：无法激活已激活的插座

我的路由器有这个问题，所以我的应用程序由一个主页组成，每当我导航到一个孩子并重新加载我遇到这个错误的页面时，这个主页上都有很多孩子

但不幸的是，这并没有解决问题，我也找不到其他解决问题的办法

    path : 'home' ,
    component : HomepageComponent ,

    children : [
      {
        path:'agent_accueil',
        component:AgentAccueilComponent,

      },
      {

        component:TechComponent,
        children:[

        } ,

当我显示事件结果时，我发现最后一个孩子被存储了，所以我想知道是否可以清除它或启动路由器，如果不可能，我如何解决这个问题

      <mat-toolbar  >
        <span class="item" routerLink="/home/profil" >Profil</span>
        <span class="item" routerLink="/home/performance">Performance</span>
      </mat-toolbar>
      <!-- some code-->
      <router-outlet  ></router-outlet>
