I think it was fixed, but either way, here is a temporary fix:
decrease render distance during the storm
after the storm leave wherever you're hiding and run around 100/150 blocks in one direction (200 if you really want to be cautious, but way less should be sufficient); do not engage with any enemies
run back (they all will have despawned)
normalize render distance (tbh idek if that step was necessary but you can do it anyways if you have need for extra caution)
