The error I get after the crash

I have tried 3.0.0-rc.9 and rc.8 and they kind of reduce the probability of issue but they do not fix it. Also, they introduce another bug shown below. So basically, they just make the crash non-deterministic.

Steps to reproduce

1. Use npx create-expo-app to create a new Expo app
2. Install reanimated + expo-dev-client
3. Build using EAS or npx expo prebuild + npx expo run:ios
4. Open the app
5. Press the "R" key rapidly in quick succession on the keyboard a couple of times
6. You will most definitely experience a crash

@EvanBacon It's weird that this crash only happens when I use expo-dev-client and not when I use Expo Go with the same versions of everything (repro provided above). Tagging you in case you know something about this.

@ansh did you get any solution? I am getting same error.

We are seeing the same issue here. Anyone found a solution?

[sangameshsomawar]

It got resolved after running watchman watch-del-all and yarn start --reset-cache

[xanderdeseyn]

Doesn't seem to fix it in our case

that did not work for me either.. 😢

I have narrowed it down to be because I'm doing some runOnJS(feedback)({ skipPlatform: ['web'] }) to trigger haptic feedback. It worked a while for me to convert the gesture to do .runOnJS(true)

const feedback = (options?: { skipPlatform?: (typeof Platform.OS)[] }) => {
    if (options?.skipPlatform?.includes(Platform.OS)) return
    try {
      throttleFeedback()
    } catch (error) {
      Sentry.Native.captureMessage('failed JS thread (haptic) feedback on Chart', 'warning')
    }
  }
  const panGesture = Gesture.Pan()
    .runOnJS(true) // https://docs.swmansion.com/react-native-gesture-handler/docs/2.3.0/api/gestures/pan-gesture/#runonjsvalue-boolean
    .onBegin((event) => {
      scrollX.value = event.absoluteX
      labelViewOpacity.value = 1
      pointDate.value = processedData[index.value].date
      pointValue.value = processedData[index.value].value
      feedback({ skipPlatform: ['web'] })
    })

but now that does not seem to work any more. 🤷‍♂️
