@6point022 I know this isn’t a solution to the actual problem you’ve reported. But just try clearing the app’s data and using the app. You would not experience the crash.

Yeah, a lot of programmers on stackoverflow also said that it works for them as well, but I was stuck on that for days and all these steps helped me out. Happy coding 👍
