The process buffer, apart from some obviously irrelevant cleaning up of the recentf list, says:

Warning (server): Unable to start the Emacs server.
There is an existing Emacs server, named "server".
To start the server in this Emacs process, stop the existing
server or call `M-x server-force-delete' to forcibly disconnect it.
Symbol's value as variable is void: org-export-async-debug

Sorry, that's pretty much just what I already said…
