At the European Championships Schäfer qualified to the balance beam final in second place behind Nina Derwael of Belgium. The German team did not qualify to the team final after Griesser and Voss fell numerous times off of the balance beam. During the balance beam final Schäfer fell off the apparatus while performing her eponymous skill and finished sixth. In September Schäfer competed at the German World Trials where she only competed uneven bars, balance beam, and floor exercise – on which she had a bad fall and injured her ankle. She recorded the highest balance beam score and second highest uneven bars scores of the competition. Later that month Schäfer competed at the German National Championships but only competed on uneven bars due to her injury. While she was in contention for the team to compete at the 2018 World Championships, Schäfer decided to withdraw due to her bone marrow edema holding her back from being able to compete at the necessary level for the World Championships.
