Angular独立组件(使用LoadComponents)懒惰加载服务不工作

该服务在组件中不起作用.并且在控制台上没有错误.保持组件继续加载.当我从组件中删除该服务时，它开始正常工作.懒惰加载组件中的服务懒惰加载存在一些问题.请帮忙.

我的服务是Timingscreen.service.ts文件

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

@Injectable({
  providedIn: 'root'
})
export class TimingscreenService {}

我的路由文件是

export const routes: Routes = [
{
    path: 'timingscreen',
    loadComponent: () => import('./screens/timingscreen/timingscreen.component').then(c => c.TimingscreenComponent),
    title: 'Timing screen',
}]

和我的组件timingscreen.component.ts

import { Component, Inject, OnDestroy, OnInit, effect, inject } from '@angular/core';
import { TimingscreenService } from '../../services/timingscreen.service';
        @Component({
      selector: 'app-timingscreen',
      standalone: true,
      imports: [],
      providers: [TimingscreenService],
      templateUrl: './timingscreen.component.html',
      styleUrl: './timingscreen.component.scss'
    })
    export class TimingscreenComponent implements OnInit, OnDestroy {
    private timingService = inject(TimingscreenService)
    }
