NG0200 is a circular DI issue : https://angular.dev/errors/NG0200

Also you should disable optimisations in devmode to get more error details.

Wouldn't it be possible to put a clear error message for a circular DI ?
Il ne serait pas possible de mettre un message d'erreur clair pour un circular DI ?
