I encountered this too. I found that if you look roughly 45° left or right you start moving again, and also if you stop and press forwards again. I have also uploaded a clip demonstrating this.
I also found my horse died when dismounting, luckily I found these reports before doing so and backed-up my save, tried it and sure enough the horse died 😞 I reloaded the backup and instead dismounted in water and the horse survived, so if you can do that.
