Horse taking damage for no reason

Issue = I was travelling with my horse in the night. And at the sudden, I can't go much further. It was like being blocked by barriers. Then, I left from the horse, and then the horse seems to get suffocation damage. I hit the ride button, but didn't work. And then, I can't interract with my horse. I restart the game, and then my horse gone.
