test_with_coverage not exiting on Windows Github actions with Dart 3.4.0

[dcharkes]

We use the following configuration for GitHub actions to collect coverage.

      - name: Install coverage
        run: dart pub global activate coverage

      - name: Collect coverage
        run: dart pub global run coverage:test_with_coverage

      - name: Upload coverage
        uses: coverallsapp/github-action@3dfc5567390f6fa9267c0ee9c251e4c8c3f18949
        with:
          flag-name: ${{ matrix.package }}_${{ matrix.os }}
          github-token: ${{ secrets.GITHUB_TOKEN }}
          parallel: true

Since a week, the Collect coverage step is no longer exiting on the Windows GitHub actions. On Linux and MacOS it's working fine.

Any ideas what's going on?

The last successful run was also on coverage 1.8.0, so I don't believe it's something to do with the coverage package itself.
