I at last am enable to test on my windows 10. I actually got error.
- It doesn't cause error on FreeBSD 13 with gs 9.54.
- It does cause error on Windows 10 with even with gs *9.53.3*, which
  comes with TL2021.
- It works without error on Widows 10 with gs 9.50 which came with
  TL2020.

I think this is not a fault on AUCTeX side. On windows, "pdf2dsc"
command just fails with similar error:

So it is strongly suspected that pdf2dsc is broken on windows, after
some point of gs 9.50. Maybe ghostscript folks doesn't check the
availability of pdf2dsc on windows when they release new version?
