This happened when I started to play a horde game:

Ah yes, the horde NNUE is not compatible with fairy-stockfish 14. Replace the fairy-stockfish download with:

RUN wget https://github.com/ianfab/Fairy-Stockfish/releases/download/fairy_sf_14_0_1_xq/fairy-stockfish-largeboard_x86-64-bmi2
RUN mv fairy-stockfish-largeboard_x86-64-bmi2 engines/fairy-stockfish && chmod +x engines/fairy-stockfish
