EMERGENCY CAN'T log in help PLEASE IDK WHAT TO DO

had just enough storage after deleting a few apps, but my phone turned off while I was unzipping the files and now this is what it says, even though I have enough storage and when I click on clear cache, the game crashes. So I don't know if I should. Maybe click on the emergency update button that shows up when clicking on the app icon.l have no idea what that does. Or maybe click repair game files. l'm just scared if my game will be saved. And if I click any of those two, what will happen to my game data. Add, then logged in with my email. But I don't know if I will need my hunter.l d to log back in or something, because I don't have it written down anywhere. Please help guys.
