In what would prove to be their final competition of the season, Boikova/Kozlovskii entered the 2020 European Championships as the title favourites, and won the short program with a new world record score. Winning the free program as well by a wide margin, they took the gold medal. Despite this success, both described it as "one of the hardest free skatings we’ve done recently." They had been assigned to compete at the World Championships in Montreal, but those were cancelled as a result of the coronavirus pandemic.
