Same problem as in #14094

There is no https://repo.msys2.org/msys/x86_64/libiconv-1.16-1-x86_64.pkg.tar.xz, but https://repo.msys2.org/msys/x86_64/libiconv-1.16-2-x86_64.pkg.tar.zst on the server

Looks like your system has disabled the non-ssl download.
Please uzip and put this to VCPKG_ROOT/downloads and try again.
