This sounds like low level issue as The error shows. What Windows version are you using? Since this IS a low level crash we don't really know what IS happening behind The scenes.
i'm on Windows 10 family.
it every time a big attack is launch, right after it hit the game crash.
it's the only time i crash, always when i use aqua jet or my Pokémon is touch by a big attack.all my driver are updated and same as the OS.
Now that i am looking at The error, i see IT tries to reallocate memory but fails For some reason, giving unregonized block error
