The 7-man endgame arose at move 55 where White has just captured f3xe4 to maintain a passed pawn and will hope to squeeze Black and win his pawn eventually or else support the advance of his e-pawn. Nevertheless Black should hold the draw and the situation is not yet critical.
The first defensive error came at move 64 although the reason why the move was inferior is far from obvious.
White now had a winning position but slipped up at move 72, and only won because a further defensive error at move 74 gave him a second chance.
Black never wants to play ...g5 because then three pieces could attack it and only two could defend it. Eventually he tried to poush the pawn in despartion but it failed.
