Please provide the steps to reproduce the issue [Bug Report only]

Create a component that injects a number via an injection token:

const MY_NUMBER = new InjectionToken<number>('my-number');

@Component({
  selector: 'app-component',
  standalone: true,
  providers: [{ provide: MY_NUMBER, useValue: 42 }]
})
export class AppComponent {
  readonly myNumber = inject(MY_NUMBER);
}

Using the chrome debugger shows it coming from valueToLabel inside component-tree.ts. It's trying to call <number>.startsWith('_'):

Please provide the expected behavior vs the actual behavior you encountered [Bug Report only]

I'd expect the component details to display normally.

Please provide a screenshot if possible [Bug Report only]

This fails with e.startsWith is not a function:

The devtools window displays nothing:
