Hi @onkarmonks, it's a bit hard to see from just a stack trace where the issue is coming from. An ANR is most if the times the issue due to the main thread, which is responsible for updating the UI, can't process input from the user, or isn't able to draw. There are multiple reasons why an ANR can happen, and multiple methods you can solve an ANR issue. Maybe this documentation can help you out a bit better finding the issue.

Let me know if you worked it out, or if you're still facing the issue!
