You are right, it seems to be a bad interaction with EDE. The crucial
point is this:

>   file-truename("/scpc:io.local:/private/tmp/emacs-mac-mrNX/")
> ede-directory-get-toplevel-open-project("/var/folders/b2/w0_x7_854hz82sbrdxqqd6gr0000gn/T/")

Reading `ede-directory-get-toplevel-open-project', there are two calls
of `file-truename'. It is not obvious to me, why a remote directory is
used as argument for one of the calls. Maybe you could debug

One wild guess: the remote directory looks like a remote temp
directory. Tramp changes temporarily the value of
`temporary-file-directory'. Since the EDE actions are invoked by a
timer, it could happen that they are applied at time when Tramp has
overwritten that variable.

Another guess: Tramp might have changed temporarily `default-directory'
to that remote directory during execution of your asynchronous shell
command. And EDE uses that value, becauses it jumps in by the timer.

Best regards, Michael.
