The OP used an email address that cannot be replied to.  Could someone
here who uses WSL (or some other setup where emacsclient on Windows
talks to the server on Unix) please try this patch with the recipe in

  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=65812#5

and report back?

If no one can test this within a week or so, I'm going to install this
on the emacs-29 branch regardless.  TIA.
