🐛 IOS - App crashes when calling JS function inside frameProcessor on React Native 0.79

[prpgan]

What's happening?

The app crashes when trying to call runOnJS (or any JS function) inside a frameProcessor in react-native-vision-camera(I am using react-native-text-recognization) plugin.
If I only log using console.log(frame) inside the frame processor, the app works fine, but any attempt to call a JS function immediately causes a crash (no red screen, hard crash).

I have tried using, runOnJs from reanimation as well as worklets, no fix found.

Below is the code where the issues shows in Xcode:
jsi::String JSCRuntime::createStringFromUtf8(
const uint8_t* str,
size_t length) {
std::string tmp(reinterpret_cast<const char*>(str), length);
JSStringRef stringRef = JSStringCreateWithUTF8CString(tmp.c_str());
auto result = createString(stringRef);
JSStringRelease(stringRef);
return result;
}

Reproduceable Code

import React from 'react';
import { StyleSheet } from "react-native";
import {
  Camera,
  useCameraDevice,
  useFrameProcessor,
} from "react-native-vision-camera";
import { useTextRecognition } from "react-native-vision-camera-text-recognition";
import { runOnJS } from 'react-native-reanimated';

function App() {
  const device = useCameraDevice('back');
  const options = { language : 'latin' }
  const {scanText} = useTextRecognition(options)
      const logFrameProcessorCalled = () => {
        console.log('FrameProcessor called');
    };

    const frameProcessor = useFrameProcessor(() => {
        'worklet';
        runOnJS(logFrameProcessorCalled)();
    }, []);

  return (
    <>
      {!!device && (
        <Camera
          style={StyleSheet.absoluteFill}
          device={device}
          isActive
          mode={'recognize'}
          frameProcessor={frameProcessor}
        />
      )}
    </>
  );
}
export default App;

babel.config.js

module.exports = {
plugins: [
'react-native-worklets-core/plugin',
['react-native-reanimated/plugin', { processNestedWorklets: true }],
],
presets: ['module:@react-native/babel-preset'],
};

This is fixed in this commit but yet to be released.

Try patching for now.

The application crashes if I send this to the frameProcessor={frameProcessor} prop. If I try to delete the props, the application functions properly without props

const frameProcessor = useFrameProcessor((frame) => {
        'worklet'
        // scheduleOnRN(() => {
        //    console.log("frame processor called");
        // })
        // const objects = detectObjects   (frame)
        // const label = objects[0].name
        // console.log("Frame running"); // OK (string only)
    }, [])

@prpgan how did you solve this issue

Unfortunately this makes the package unusable at the moment

Really struggling to get frameProcessors working on production because of this
