Inizia da src/PowerShellEditorServices/Services/DebugAdapter/DebugService.cs intorno alla riga 390, quindi riproduci i passaggi segnalati con il PSCustomObject annidato durante il debug. Traccia il percorso di SetValue quando modifichi NestedField e verifica che l’aggiornamento venga completato senza l’errore di cast da VariableDetails a VariableContainerDetails.
