Yes, it is a pity that there's no newer prebuild Emacs for MS Windows.

I can reproduce it with that Emacs snapshot from January, although the
error message is different. However, with a recent Emacs 28.0.60 build
it works for me. Bothe cases I have called "emacs -Q".

There have been several fixes for Tramp on MS Windows this
year. Therefore, I recommend you install Tramp 2.5.1.3 from GNU ELPA.

According to the method completion, I have no problem with the latter
Emacs, once Tramp is loaded.
