Just for context, the new version `org-element-cache-map' uses a new
macro `org-element-with-enabled-cache' that temporarily enabled cache
for the duration of `org-element-cache-map'.

This sounds like you got mixed Org installation or org-element.el from
built-in Org. If it is the case, you may need to check your config.

You can also try WIP branch feature/shadowcheck that tries more to fight
