After winning a second national title, Guignard/Fabbri competed at the 2020 European Championships and placed third in the rhythm dance, winning the small bronze medal. They were scheduled to skate last in the free dance, which became a protracted wait following technical issues in assessing the score for penultimate team Papadakis/Cizeron. Placing fourth in that segment, they dropped to fourth place overall. They had been assigned to compete at the World Championships in Montreal, but these were cancelled as a result of the coronavirus pandemic.
