TurboModule which uses JSI crashes with `this` memory address 0x1

[jihoobyeon]

Problem Description

I'm trying to port BabylonReactNative to TurboModules,
but when I made codegen and run the app, it crashes with memory address of this(at facebook::jsi::Object) is 0x1 - absolutely abnormal address value.

I've also questioned it at Babylon.js forum, but there is no abnormal address value in BabylonNative part, so I guess JSI of RNW seems to be problematic, thus asking here.

This is the call stack:

BabylonModule.dll!facebook::jsi::Runtime::getPointerValue(const facebook::jsi::Pointer & pointer) line 81
BabylonModule.dll!winrt::Microsoft::ReactNative::JsiAbiRuntime::AsJsiObjectRef(const facebook::jsi::Object & obj) line 817
BabylonModule.dll!winrt::Microsoft::ReactNative::JsiAbiRuntime::getProperty(const facebook::jsi::Object & obj, const facebook::jsi::String & name) line 515
BabylonModule.dll!facebook::jsi::Object::getProperty(facebook::jsi::Runtime & runtime, const facebook::jsi::String & name) line 94
BabylonModule.dll!facebook::jsi::Object::getProperty(facebook::jsi::Runtime & runtime, const char * name) line 90
BabylonModule.dll!facebook::jsi::Object::getPropertyAsObject(facebook::jsi::Runtime & runtime, const char * name) line 174
BabylonModule.dll!facebook::jsi::Object::getPropertyAsFunction(facebook::jsi::Runtime & runtime, const char * name) line 188
BabylonModule.dll!napi_env__::napi_env__(facebook::jsi::Runtime & rt) line 51
BabylonModule.dll!Napi::Attach(facebook::jsi::Runtime & rt) line 7
BabylonModule.dll!BabylonNative::ReactNativeModule::ReactNativeModule(facebook::jsi::Runtime & jsiRuntime, std::function<void __cdecl(std::function<void __cdecl(void)>)> jsDispatcher) line 42

Steps To Reproduce

1. Make a new arch RNW app.
2. Add modules described below and run yarn react-native autolink-windows.
3. Change App.tsx as below and run the app.

import { JSX, useEffect, useState } from 'react';
import { View } from 'react-native';
import { Camera, Scene } from '@babylonjs/core';
import { EngineView, useEngine } from '@babylonjs/react-native';

export default function App(): JSX.Element {
  const engine = useEngine();
  const [camera, setCamera] = useState<Camera>(null);

  useEffect(() => {
    if (engine) {
      const scene = new Scene(engine);
      scene.createDefaultCamera(true);
      setCamera(scene.activeCamera!);
    }
  }, [engine]);

  return (
    <View style={{ flex: 1 }}>
      <EngineView style={{ flex: 1 }} camera={ camera } />
    </View>
  );
}

Expected Results

Just run without error.

@jihoobyeon, I will check it out next week.
Did you debug it yourself? What did you see under the debugger?

@jihoobyeon , where is the C++ code for the TurboModule and how is it being instantiated?
The repo that you pointed to has only a set of new JS files.
My understanding is that Babylon Native does not have it working for RNW, and I do not see how can you achieve it without changes to C++ code.

C++ codes are located at branch module and view.
Yup, I knew it was a bad practice to split codes just by git branches, but I was on haste with a reallife issue at that time. I apologize. So I now made them to separate repo:
"@babylonjs/react-native-windows-module": "https://github.com/jihoobyeon/BRN-windows-module.git"
"@babylonjs/react-native-windows-view": "https://github.com/jihoobyeon/BRN-windows-view.git"

And yes, BabylonReactNative used to work for RNW, but broken after RNW 0.71.
Thus I am trying to fix C++ codes, but the very first error I encounterd is this this memory violation.

Debug console only says: exception throwed: read access violation. **pointer** was 0x1.
but at Visual Studio (the tab name is "auto" for Korean - I think it's translation error), this at line 94 of jsi-inl.h is 0x0000000000000001, thus results failing to read memory at JsiAbiApi.cpp.
So it seems to facebook::jsi::Object *obj not has been made while initialization.
I have to know what is that obj and why it is not properly made to take next step.

@vmoroz , Have you checked it?
Did you find anything suspicious?
