After winning the German title for the second consecutive year, Hase/Seegert were assigned to the 2020 European Championships, where they placed fifth in the short program with a new personal best, breaking 70 points in that segment for the first time. Fifth in the free skate as well, they were fifth overall, despite a number of errors that led Hase to deem it "not a good program." This proved to be their final competition for the season, as they had been assigned to compete at the World Championships in Montreal, but these were cancelled as a result of the coronavirus pandemic.
