[SOLVED] Typescript syntax highlighting not working

After enabling the Typoscript plugin like suggested by the IDE none of my .ts files show syntax highlighting any more.

I've tried reinstalling android studio after removing all settings folder in appdata, userprofile, program files folder. I've tried with new project and existing ones. I am not able to get the syntax highlighting back.

I'm running: - windows 10 - Android Studio 3.5

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

@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
})
export class HomePage {

  constructor() {}

}

How do I get syntax highlighting working again asif a clean installation.
