Describe the bug

Brand new application, I'm receiving argument type errors when instantiating the S3Client and assigning any operation to the .send() function.

new S3Client error:

Argument type {region: string} is not assignable to parameter type __CheckOptionalClientConfig<S3ClientConfig>

.send() command error:

Argument type ListBucketsCommand is not assignable to parameter type Command<ServiceInputTypes, SI, ServiceOutputTypes, SO, SmithyResolvedConfiguration<__HttpHandlerOptions>>

Reproduction Steps

This looks to be a continuation of #4928

Minimally reproducible application using Angular 18 via ng-cli, vanilla setup, SCSS.

home.component.ts

import { Component } from '@angular/core';
import { RouterOutlet } from '@angular/router';
import {S3Client} from "@aws-sdk/client-s3";

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [RouterOutlet],
  templateUrl: './app.component.html',
  styleUrl: './app.component.scss'
})
export class AppComponent {
  title = 'awsTester';

  s3Client: S3Client;

  constructor() {

    console.log("Testing S3...");

    this.s3Client = new S3Client({
      region: 'ap-southeast-2'
    });

  }

}
