ANR bug found in the lite version of Outlook (in Android)

Question

Description

After a series of operations on pages of 'add account' or 'create account', the Outlook Lite app showed only a empty page with nothing on it, what's more, I can't do any operation on the empty page, can't switch to another page of the app. I had to restart the app if I want to use it.

Platform and Testing Env

Pixel 8a (real device), Monkey for automatic testing, collecting api traces with Frida. The app mentioned is the latest version by now, installed from Google Play Store, Microsoft Outlook Lite, version Jan 12, 2015. I also performed a lot of testing on the full version which is Microsoft Outlook, but never meet this bug. I read the source code of both of them, and I found the implement difference, such as the page of 'add account', lite uses Fragment which is reusable, but full doesn't. If using the cleared Fragment (related api in source code), the page tends to be empty, which may be the reason of this bug.
