To prevent this from happening don't use the onImageIndexChange handler to set a state which is used on the imageIndex.

eg:

const [imageViewImageIndex, setImageViewImageIndex] = React.useState(0);
const [imageViewIsVisible, setImageViewIsVisible] = React.useState(false);

<ImageView
  imageIndex={imageViewImageIndex}
  visible={imageViewIsVisible}
  ...
/>

<Pressable
  onPress={() => {
    setImageViewImageIndex(index);
    setImageViewIsVisible(true);
  }}>
  <Image ...  />
</Pressable>

I managed to bypass this by using two index states. The startIndex is used when you press an image, it will set the initial index and open the viewer, the imageIndex is used by the ImageView to update the index.

const [imageIndex, setImageIndex] = useState<number>(0); 
const [startIndex, setStartIndex] = useState<number|null>(null);
const showImageView = startIndex === 0 || !!startIndex;

 <ImageView
  images={[]}
  imageIndex={startIndex || 0}
  onImageIndexChange={setImageIndex}
  visible={showImageView}
  />
