Fails to build on Windows with GHC 9.6.1

[Minoru]

I attempted to add GHC 9.6.1 to our CI config, but the build of 6791e77 fails on Windows 2022 with:

There is a report against the network package haskell/network#544, but it was closed without any satisfactory resolution. It's possible that GitHub Actions is the one at fault, but I'm not sure. FWIW, the build passes on Ubuntu 22.04.

There is also this issue in the Cabal repository: haskell/cabal#8858. I am getting similar error messages with the new GHC 9.4.5. I don't think it is GitHub Actions-related; I'm getting these messages locally.

I did ask at GHC's repository: https://gitlab.haskell.org/ghc/ghc/-/issues/23309.
