Version

9.5.0

Steps to Reproduce

Run the app from the repo on Android emulator

Tap on the Input field, rapidly enter text, rapidly tap on + button and then back button, basically just go a little bit crazy. That should do the job (see the video attached)

Note:

  • Couldn't reproduce it on a real device.
  • Crash doesn't happen with Session Replay disabled.

Expected Result

Should not crash the app.

Actual Result

Crashes the app.
