After this, please tell me the value of desktop-saved-frameset in the
.emacs.desktop file.

Also after this step.

I don't understand why should this happen. Could you also please try
your recipe, but in the fist step, put this in your .emacs

   (setq desktop-restore-frames nil)
   (desktop-save-mode 1)

instead, to make sure that all problems do indeed depend on frameset
restoration.
