Da ieri si blocca il sw quando cerco di accedere in stile del modello alla funzione menu a scomparsa e mi restituisce l'errore che sotto riporto.

Questo avviene con tutti i progetti che ho e non riesco più a lavorare.

Ho reistallato il sw ma la cosa non cambia.

Qui di seguito il messaggio di errore e in allegato lo screenshot della "cosa" 

Help me
