Hi @dodiwknd!
Could you provide snack or repo with minimal reproducible example?
Could you also provide us with information in what situation does the error occur? Is it on startup or do you need to do something specific?

I've run into this issue, which seems to cover the same NPE. Can you try updating reanimated to 2.4.1?

Unfortunately I can't provide samples, this application has been built very extensively, because I don't know for sure when this will happen. I think this is happening because the animated Layout has not been rendered and the user has navigated to another page. hope this can help you

ran across the same crash recently. we started seeing it once we added an Animated.View with a layout animation. so the suggestion from @dodiwknd may be correct. excerpt from the component:

export default function UpdateHighlightsBanner() {
  const dispatch = useDispatch();
  const { dismissedBanner, updatedOn } = useSelector((store: RootState) => store.settings.version);
  const { releaseNote } = useAppUpdate();

  const releaseNotes = releaseNote.replace(/; /g, ";").split(";");
  const daysSinceUpdate = differenceInDays(today, parseISO(updatedOn));

  const handleOnDismiss = () => {
    dispatch(settingsActions.dismissUpdatesBanner());
  };

  const visible = !dismissedBanner && daysSinceUpdate <= 3 && releaseNotes.length > 1;
  if (false === visible) return null;

  return (
    <Animated.View style={styles.container} exiting={FadeOut.duration(200)} layout={Layout.delay(250)}>
      <Image source={require("./update-highlights-confetti.webp")} style={styles.confetti} />
      <View style={styles.header}>
        <Text>Some text</Text>
        <Pressable onPress={handleOnDismiss}>
          <Icon name="close" />
        </Pressable>
      </View>
      <DisplayTextList icon="check" iconColor={Theme.palette.success} list={releaseNotes.slice(0, 3)} />
    </Animated.View>
  );
}
