WP Android stops responding in some cases when editing a classic block

Expected behavior

The app should not crash/stop responding when editing these pages/posts

Actual behavior

The app crashes when these pages/posts are edited. The error message mentions: AN Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain input events that were delivered to it over 500.0ms ago. Wait queue length: 9. Wait queue head age: 18080.2ms.)

Steps to reproduce the behavior

I've been unable to replicate the behaviour on my device, but since the user is on a free WP.com plan and can replicate it on two devices, I'm pretty sure this is a bug. The user has also submitted the feedback when the app got frozen, so the crash logs should have come through too.

• Create a page with a classic block on a WordPress site
• add some content to the classic block
• try to edit that page within the WordPress Mobile app. After a while, it should crash

Tested on [Dragon Touch K10], Android [8.1.0], WPAndroid [20.4]

Also replicated on a Samsung Galaxy A20e with Android 11

Start by reviewing the reproduction steps for editing content in a classic block on WP Android, using the supplied Android 8.1 and 11 environments and the app version noted. Check the submitted feedback and crash logs for the input-dispatch timeout. Done means the freeze or crash is understood and no longer occurs when editing the described pages or posts.
