Game Crasher, "no unfainted pokemon"

So, I got into a situation where the script stopped after I lost to Anastasia, and the game asked if I wanted to save, so I did. Easy peasy yeah? Well… every time I boot up my save file from now on, it starts off right as the Anastasia battle starts, but this time, all my pokemon are fainted already, and the moment she sends out her pokemon, my game nopes itself.

Is there any way to make it so that my pokemon aren’t fainted as the battle begins?

You are an absolute legend, thank you!
