我收到 Error: NG0200: Circular dependency in DI detected for ApplicationRef. 以防万一：

import { ModalController } from '@ionic/angular';
import { MyModalComponent } from 'MyModalComponentPath';

@Injectable({
    providedIn: 'root'
})
export class MyCoreService {
    constructor(
        private modalController: ModalController
    ) { }
    
    private async openmodal(): Promise<void> {
        const modal = await this.modalController.create({
            component: MyModalComponent
        });

        modal.present();
    }
}

我也有类似的核心服务使用 ModalController 没有这个错误。

这里的循环依赖怎么可能？有人遇到过这个问题吗？
