I'm trying to buy an empty map from a cartographer, I can buy the map and put it into my inventory, but after that, the game doesn't work properly anymore. Villagers and other entities stop moving, using tools or hands on blocks just makes them disappear, any change to the environment doesn't get saved when saving, when I reload the world after trying to buy the map it just brings me back to the last save before trying to buy the map.
This also means I cannot buy maps to ocean monuments or woodland mansions because I can't progress with the trades.

Yes, seems to be the same issue, only that it happens when I try to trade the empty map, I'm not able to progress to the explorer maps.
I've recreated the world in 1.13.1 and it doesn't result in a crash anymore, just in an awful long lag (like 10-15min)
Does MC-130449 describe your issue? If not can you attach the crash report from
[minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/guides/finding-minecraft-data-folder]
. Also, the lagging is coming from MC-126244.
