On Minecraft not just one world, The moment I go to trade with villagers my game "breaks."

Once this happens I am no longer able to access chests and other workstations, get in anything, and all the entities in my game freeze. I basically just walk around and when I go to save and exit I am stuck on the Saving world Screen until I restart my computer due to the fact that I cannot close the tab.

As you can see in the picture below I am not collecting xp, the zombies aren't moving/looking at me to attack me, and I phase through the minecart without moving it. PLS HELP
