At the 2021 Russian Championships, Mishina/Galliamov entered with expectations of vying for the top of the podium, but encountered problems in the short program when Galliamov skated through his attempt at a side-by-side jump. As a result, they placed fifth in that segment. The free skate also proved difficult, with both making jump errors and Galliamov almost dropping Mishina in their final lift. Galliamov was uncertain as to why they had performed poorly, but suggested his being unwell the week before may have been a factor.
