Yeah, that’s what happened to the FPÖ in Austria. They looked bad after being in a coalition for the first time, but recently the FPÖ won the election in September. Not sure how similar the parties are though.

Brothers of Italy won the 2022 elections, have a prime minister, and are as popular as ever, even though they have softened a bit in their rhetoric I would say.

Situation with parties like the AfD is similar in many other European countries.
