This becomes more and more strange.  And the warning messages shown by
GDB about a missing DLL are also not a good sign.

Try this:

  gdb "C:\Program Files\Emacs\emacs-28.1\bin\emacs.exe"
  ...
  (gdb) set debugevents
  (gdb) run

Then post here everything GDB prints while Emacs starts up (until it
shows the initial frame) -- there should be a lot of messages about
loading DLLs.  Maybe that will tell us something.
