But the way Europe works today, that's a national issue.
Hungary and Poland had weak constitutions and lacked democratic guarantees because their constitutions were designed to be subject to change; the idea was that democratically elected officials would draft new and better conditions after a transition period, rather than having the communist parties at the table when drafting them. Unfortunately, the social democrats never bothered to change the constitution, leaving them unchanged until far right parties came to power.
In Italy there's a long tradition of election reforms from far right parties, and their politics has always been a mess. Italy has always worked in spite of, not thanks to, its political leadership, so having a de facto MSI member back in power is not such a radical change.
And bad actors have always taken part in democracy, people just need to have access to education and information to make them not vote for the Le Pens, Farages, Berlisconis, Melonis, and Orbans out there. They should be kept from controlling the media (like Berlusconi), and we need to do better to prevent foreign interference, but we cannot prevent them from participating.
