App crash on Android 12 due to expo-clipboard?

Expo Development Tools
1

While testing on App on Android 12 (Both Dev-client & Standalone) app crashes immediately after the launch without any exception log in expo debug log. However, I was managed to get the native error log with Android studio as below

Seems like the issue could be related with the expo-clipboard. Could you please help me to fix this issue?

Hi!

Could you compare your findings with this issue?

Namely, it appears others that have experienced this have primarily seen:

  • the app crash one time, and then work
  • that it’s happened mainly on Samsung devices
  • Switching to Hermes may fix it

If you’re able to make a minimal reproduction, that would be a great aid for helping us track down this issue.

Thank you!
