No problems.

I am using for now the emacs-28 version of tramp-file-name-unify to
prevent this error (it is inlined), to reproduce the bug with
helm-find-files you have to use:

(setq helm-ff--file-accessible-directory-p-fn
#'file-accessible-directory-p)


And I still have the error, here the backtrace, the tramp log at the end
of this message:
