How to fix corrupted file

okay_nick

I think my file may be corrupted. It was fine when I was playing about 24 hours ago right before I went to bed. I woke up and it hasn't been working ever since. I get notifications for Kim's Picks, but as soon as I close that menu, the game just constantly shuts down on me.While Kims Picks is still open I can open up the starshop thing, but as soon as I close that, the game shuts down. I've tried everything, uninstalling/reinstalling, resetting phone, restarting phone, nothing works. What should I do?
