I had a similar issue on a single player world running 20w12a. I received this error message after the game crashed when I equipped a map in my main hand:
ThegamecrashedwhilsttickingplayerThegamecrashedwhilsttickingplayerError:java.lang.IllegalArgumentException:Cannotgetpropertycdt{name=axis, clazz=class fr$a,values=[x, y, z]} asitdoesnotexistinBlock{minecraft:spruce_wall_sign}
I know that underneath the area where the map was loading, there are wall-mounted spruce signs that I was using for water item transportation.
I was able to work around the buggy map by switching to a slot in my main hand that did not have the map.
