How can I go back to the state before update

hey guys, I downloaded a flashcard file and changed it to the new form that I want.
but by mistake I downloaded this file again and the flash cards chaged to the original form… can I change it back to the form that I changed?



omg, thank you so much. to be honest, when I posted this post, I didn’t expected proper solution, rather I just wanted to at least try it. and I restored the flashcards what I made.
thank you again and have a nice day!
