if someone can repro the crash in house and could help to verify whether the updated jsc fixing the crash, that would be appreciated.

upgrade steps:

1. yarn add jsc-android@next
2. since the new jsc doesn’t support non-Intl variant, please update android/app/build.gradle and change 'org.webkit:android-jsc:+' to 'org.webkit:android-jsc-intl:+'

Well, I am still in the process of fixing the issue. It is still impossible for me to reproduce this issue, but there are still about 1% crashes for our Android users according to Crashlytics and Sentry.

But I did make progress which seems to have fixed this issue for a new release: I have updated to React Native 0.68.5, and enabled Hermes for Android. The crash does not re-appear up until now, but so far the rollout on Android is only done for the first 5% of the users, so it is still too early to tell for sure.
