React Native App Crashes Instantly When Entering Debug Mode when using NativeModules & JNI

[Matt-Horton]

Description

I've created a small react-native app that uses some custom c++ code and the OpenCV library and works using the JNI and Native Modules. The app works fine however when I try to debug the react native code using the in app developer menu, my app instantly crashes and I get this error in Logcat (Full stack trace in section below):

My custom c++ code only gets called once I hit a button in the app and this crashes out before I even get a chance to press the button, which leads me to believe it's an issue to do with debugging a react-native app when using Custom Modules and JNI.

This happens when I test on both a physical device (Samsung A40) and an emulator (Pixel 3a).

Has anyone encountered an issue like this before or may know what is causing this to happen?

Appreciate any guidance / help on this one.

Steps to reproduce

1. Create an app that uses Native Modules to call a native method which uses JNI to call a method in c++.
2. Run the app in debug mode and open the developer menu
3. Select "Debug" from the developer menu
4. App instantly crashes

Same issue with 0.72.7

[Dineshmani3]

I am facing the same issue with react-native 0.72.1. I have even tried with 0.72.0 and then upgraded to 0.72.2. None of them works. Does anyone found a solution for this? Please let me know and it would be helpful. Thanks in advance.

I'm seeing the same issue, I also used JSI to bridge to OpenCV.
