I cannot reproduce with your minimal example, but the error indicates
some issue with persistent cache. Can you:

1. Go to cache directory (~/.cache/org-persist)
2. Open "index" file and find the record for your minimal file and find
   :persist-file property. That property is relative cache file path.
3. Attach the contents of the :persist-file

Then, can you delete your cache folder and try to reproduce again?

By the way, did your Emacs crash recently?

I cannot reproduce this as well. The fact that "Current command: nil" is
suspicious. Is "C-c *" bound to org-ctrl-c-star for you?
