I cannot reproduce this.  I tried this on several Windows systems and
several Emacs versions, including Windows 10 and Emacs 30, and I don't
see the hang.  (I don't have a Windows 10 system with Emacs 30, so I
tested there with an older version, but unless you are saying that
this happens only with Emacs 30 and only on Windows 10, I don't think
this matters.)

Tell me, does the directory "~/.emacs.d/" exist on that system?  If
you type "C-x C-f ~/.e" and press TAB, do you see ".emacs.d" among the
completion candidates?

Another thing to check is whether you customized your Windows system
in a way that affects the "open" operation on directories.

Also, what happens if you type

  M-: (w32-shell-execute nil "~/.emacs.d/")

?
