Add any other context about the problem here.

Riproduci il problema eseguendo il flusso di training di Model Builder fino a Finalizing the Model. Inizia da src/Microsoft.ML.ModelBuilder/Utils/Utilities.cs alla riga 408, quindi traccia le chiamate dalle righe 1195 e 1120 di TrainViewModel.cs. Il lavoro è completato quando il training termina senza l'errore di riferimento null e il modello termina di essere generato.
