I see. Anyway, the patch of tramp-unload-tramp is useful, thanks for the
test case.

I've done this, installing the packages from MELPA, and the error
occurs also for me. This test gave me the chance to debug further
(tramp-unload-tramp doesn't leave enough Tramp code for debugging :-)

Finally, I found the culprit in tramp-initial-file-name-regexp. I've
fixed this, and now counsel-find-file works properly.

The bad news for you is still, that it changes an autoload object. That
means, you will see the fix only with a recent checkout of Emacs 27.0.50.
OTOH, Emacs 27.0.50 will start the pretest soon; an Emacs 27.1 will
appear within some few months. Hopefully.

Best regards, Michael.
