React Native Crashlytics iOS Crash: "Unhandled JS Exception: TypeError: Restricted in strict mode, js engine: hermes&am

I'm encountering a crash in my React Native app. The crash report from Crashlytics indicates an unhandled JavaScript exception with the following error:

I'm trying to determine the root cause but haven't found a clear explanation yet. Here are some details about my setup and what I've tried so far:

• React Native Version: 0.72.6
• Crash Context: The crash is reported on Crashlytics in production after and update and I have not been able to reproduce it consistently during development.
• Error Detail: The error message states "Restricted in strict mode". I suspect this may be related to some JavaScript code that is violating strict mode restrictions, but I'm not sure which part of the code might be causing it.
• Investigation: I've searched for similar issues with the Hermes engine and strict mode, but haven't found a definitive answer or reproduction scenario.

Questions:

• What could cause the "TypeError: Restricted in strict mode" error in a React Native app using Hermes? Are there known pitfalls or common coding mistakes (or library issues) that trigger this error?
• What debugging strategies or tools can I use to isolate the problematic code since the error only appears in production?

Any insights, similar experiences, or suggestions on how to track down this issue would be greatly appreciated!
