Angular HttpClientModule error - The declaration was marked as deprecated here

In Angular-19 no-standalone project I got this error:

The declaration was marked as deprecated here.

and HttpClientModule is highlighted in Core.Module

MAIN CODE:

App.Module:

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

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { SharedModule } from './shared/shared.module';
import { BootstrapModule } from './shared/boostrap.module';
import { CoreModule } from './core/core.module';

@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
AppRoutingModule,
SharedModule,
BootstrapModule,
CoreModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }


Core.Module:

import { NgModule, Optional, SkipSelf } from '@angular/core';
import { CommonModule } from '@angular/common';
import { HTTP_INTERCEPTORS, HttpClientModule } from '@angular/common/http';
import { JwtInterceptor } from './interceptors/jwt.interceptor';
import { ErrorInterceptor } from './interceptors/error.interceptor';
import { LoadingInterceptor } from './interceptors/loading.interceptor';

@NgModule({
imports: [
CommonModule,
HttpClientModule
],
providers: [
{ provide: HTTP_INTERCEPTORS, useClass: JwtInterceptor, multi: true },
{ provide: HTTP_INTERCEPTORS, useClass: ErrorInterceptor, multi: true },
{ provide: HTTP_INTERCEPTORS, useClass: LoadingInterceptor, multi: true }
]
})
export class CoreModule {
constructor(@Optional() @SkipSelf() parentModule: CoreModule) {
if (parentModule) {
throw new Error('CoreModule is already loaded. Import it in the AppModule only.');
}
}
}
