🔥[CRASH] Android 9 and libjsc.co crashes on RN0.60.4

Hi, First of all a big thanks to this great community that develops this amazing platform. You are all doing an amazing work!

Now to the issue: We rolled out our app with RN0.60.4 to our users and are experiences some crashes across a multiple range of Android devices all running Android 9. We do not have Hermes enabled as it is not stable for us at the moment.

Affected devices:

• OnePlus 6 & 6T
• Google Pixel 3
• Xiaomi POCO F1
• Samsung Galaxy S9

Here is an example stacktrace we collect through Crashlytics, unfortunately not very verbose:

Steps To Reproduce

We are unfortunately not able to reproduce it locally but I am sure we are not the only one with this problem. This has not been before with RN0.57.8

Describe what you expected to happen: Android should not crash.

A couple of weeks ago our project had a crash report on some devices because of Hermes, so I disabled it. Now we have a report on other devices because of JSC and the solution is switch to Hermes. Life is endless pain.
