@gurbela Not able to repro it on latest version. I am using a scrollView with lots of items.
Can you share your App.tsx file?

  const scrollHandler = useAnimatedScrollHandler({
    onScroll: event => {
      const y = event.contentOffset.y;
      translateY.value = y > 0 ? y : 0;
      scroll.value = y;
      shouldClose.value = y > 0;
    },
  });

<Animated.FlatList
        nestedScrollEnabled
        data={['']}
        ref={sectionListRef}
        refreshControl={<RefreshControl refreshing={refreshing} onRefresh={handleRefresh} />}
        onScroll={scrollHandler}
        contentContainerStyle={styles.sectionListContent}
        showsVerticalScrollIndicator={false}
        renderItem={renderLists}
        maxToRenderPerBatch={1}
        removeClippedSubviews={true}
      />

I'm using scrollHandler, and it causes this error (a crash)

@gurbela please create a reproducer using this template. We cannot look into issue if they are not created with it.

Also, it is unclear if this is related to The New Architecture or not. We have a template to collect New Architecture issues that should be used if that's the case.
