Software and hardware versions

Android v9, device used - Realme X2 pro

Problem description

App crashes due to java.lang.reflect.InvocationTargetException
at java.lang.reflect.Method.invoke(Native Method)
The activities crash while performing a specific task twice.

Steps to reproduce the problem

While sending any form, if you click send it will take you to activity_send. Now if back button is clicked and we revert back to the previos activity where forms were to be selected and if we click send again the app crashes and we are back to home screen.

Expected behavior

After solving the issue, upon clicking send again, the activity won't crash and will take you to the required send_activity.
