I looked into the problem and it seems that it’s not caused by the duplication itself.
The problem here are the characters specyfic to Polish alphabet. I was trying to put them in Menu Name of the new post type. Although the post type is created, trying to do anything with it (editing, duplicating etc.) results either in Invalid post type or Unrecognized post_type error. Every existing custom post type is erased in both cases.
Sorry for causing a commotion if the problem was already known.

I was able to execute an export, but my data wasn’t in it, as if the plugin was used.
Fortunately, knowing where to look, I was able to replace the record in the database with the one from my most recent backup and recover most of the data. It saved me a lot of work, thanks.
