Setup on windows-2019 fails with: "Could not find a part of the path 'D:\Include\ucrt\module.modulemap'."

My Windows ci.yml just started failing yesterday (since https://github.com/compnerd/gha-setup-swift/commit/17be5ca66ad69b44177f01b6b0b23575d3d7791a):

  windows:
    runs-on: windows-2019
    steps:
      - uses: compnerd/gha-setup-swift@main
        with:
          branch: swift-5.9-release
          tag: 5.9-RELEASE
      - uses: actions/checkout@v4
      - run: swift test

Here's the error:

That implies that $env:UniversalCRTSdkDir and $env:UCRTVersion are undefined. This would imply that the gha-setup-vsdevenv didn't trigger or saving the environment went wrong.

@marcprux can you point me to one of the failing runs?

Here's a failure with windows-2019: https://github.com/skiptools/swift-sqlcipher/actions/runs/14509591122

Then I bumped it to windows-2022 (and Swift 6.1, but I doubt that is relevant) and it passed: https://github.com/skiptools/swift-sqlcipher/actions/runs/14515775453

In case it helps, I had a similar issue and bumping to windows-2022 did not fix the issue for me, but switching to Swift 6.1 seems to have...

See windows-2022 with swift-6.0 which failed at https://github.com/drmohundro/SWXMLHash/actions/runs/16005946083/job/45152541496

And see windows-2022 with swift-6.1 which succeeded at https://github.com/drmohundro/SWXMLHash/actions/runs/16006037532/job/45152845289

I ended up removing swift-5.10 for now.
