Steps To Reproduce

Can’t reproduce it reliably, I’ve received tens of crashes on Crashlytics though.

Describe what you expected to happen:

Not a crash.

Snack, code example, screenshot, or link to a repository:

This is the crash:

Fatal Exception: com.facebook.jni.CppException: JS Functions are not convertible to dynamic

FTR, this issue seems to be similar to https://github.com/facebook/react-native/issues/25784 but there is no 3 callback method involved as far as I can tell.

I’ll repost my comment from #25784: This crash has been happening over the last 2-3 months and I’m on RN 0.61.X as well. Honestly gave up on it and decided to suck it up. Sucks for the users though.
