From the error message it looks like the issue is that the version of
Windows you're using doesn't like the Lets Encrypt certificate that
postgresql.org uses.
The fix is probably to update your root certificates, using a package
Microsoft provide. I'm not too familiar with the Windows UI so I
don't know whether there's a way to explicitly trust a certificate -
if there is, trusting the one for www.postgresql.org would fix it too.
If there's a newer version of stack builder available for download
that might be worth trying too, in case they've worked around the
issue.
