INDS not opening

[vflavored]

Hi, been playing Pokémon soul silver for a couple days and everything was good (except the sprites becoming black squares sometimes ) but now suddenly the app doesn’t open anymore and when I try to do it it takes me back to the home screen. I literally don’t know what to do since the certificate is authorized and it worked till couple hours ago. Please help me to solve this I don’t wanna lose all the progresses and saves, plus I don’t know where they are actually saved . Thank you a lot .
