Looks like the CI failure is unrelated?

Yeah, the Julia 1.4 distribution for MacOS is broken. I'd suggest adding a exclusion:

        exclude:
          - os: macos-13
          - julia-version: 1.4

Also probably a good idea to switch back to macos-13 for now, macos-latest got switched to ARM machines or something recently.

Did you mean switching to macos-latest (which is currently excluded) instead of macos-13?

I meant using macos-13 globally and excluding Julia 1.4. I've also been using the juliaup action recently -- here's how that would look like

...
    strategy:
      matrix:
        julia-version: ['1.0', '1.1', '1.2', '1.3', '1.4', '1.5', '1.6', '1.7', '1.8', '1.9', '1.10', '1.11']
        os: [ubuntu-latest, windows-latest, macos-13]
        exclude:
          - os: macos-13
          - julia-version: 1.4
    steps:
      - uses: actions/checkout@v4
      - uses: julia-actions/install-juliaup@v1
        with:
           julia-version: ${{matrix.julia-version}}
...

Thanks. I have updated the CI
