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

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

Start by reproducing the crash in the linked image-processor repository with React Native 0.72.0, using the developer menu's Debug action and capturing Logcat. Inspect the Native Modules and JNI path alongside the RuntimeSchedulerBinding stack frame. Done means identifying the cause and confirming that entering debug mode no longer crashes on the reported device and emulator setups.
