Yes. So when it first happened my siblings were playing Minecraft split screen. I believe it was just a survival world. And everytime they would hit each other and cause damage the game would then shut off completely crashing the game. And when me and my brother were in Minecraft on my realm when we would hit eachother it would make it so then no players or other mobs were moving. You could not damage and entity’s or interact with them. You could not open doors. Click button or pull levers. You couldn’t use purserplates. You couldn’t open your inventory or open any storage blocks inventory either. It seems that when you hit the player they also took no damage everything would just lock and no longer work. Only thin you could do was move around. After leaving the realm it would take about 10 minutes or longer before you could join the realm again. After turning friendly fire off it would make it so that fixes the problem for now. But you have to keep it off or otherwise the glitch would happen when hitting someone. 

One thing I’ll say for sure is it totally is annoying and I understand your frustration. I’m not sure if it’s a proper bug or what. But if you didn’t know bedrock seems to have a problem with chunk deleting entities. Pretty much if you have a farm that’s built into two chunks. There ends up being a chance that if the entity is on the border of the chunk it can end up deleting it. It’s definitely a frustrating problem but there are ways to work around it. If you look up some videos on YouTube about chunk deleting hopefully that’ll help you out. Pretty much though if you build your farms within the chunk you shouldn’t have to worry about any of your animals being deleted. And I’m sorry that you’re dealing with this annoying bug.
