Realm Freezes

The game freezes when users with armor with enchantments protection 4 unbreakable 3 repair 1 and thorns 3 hit each other the game freezes and can not open or the inventory and apparently it crashes and when I leave the realm it does not allow me to close it until after 30 minutes and after closing the kingdom and reopening it, it is restored but the same thing happens again if the users with armor enchanted with the enchantments named above are hit again and the game freezes and crashes again.
