tramp-sh-handle-file-exists-p should never be called with "/ssh:", it
isn't a remote file name. As the error message says. This is not a new behavior.

Yes, this has been changed for the benefit of Tramp method, user and
host name completion. See bug#37954, bug#51386, bug#52758, bug#53513,
bug#54042 and bug#60505.

I don't use ivy-mode. Could you pls give me a recipe that I can
reproduce?

Do you know another completion system which is affected?
