Got the same. But as a "quick fix" you can just remove the devDependencies out of the package.json.
But there are still a few npm packages that need attention, but its working for now.

The 'stylelint-config-standard' latest is 40.0.0 (as Jan 15, 2026), which has a dependency of Stylelint 17, however the latest 'grunt-stylelint' (0.20.1) still uses Stylelint 16.

Workaround is to edit the package.json file, and specify stylelint-config-standard 39.0.0, which still uses Stylelint 16.

"devDependencies": {
    "grunt": "latest",
    "grunt-eslint": "latest",
    "grunt-jsonlint": "latest",
    "grunt-markdownlint": "latest",
    "grunt-stylelint": "latest",
    "grunt-yamllint": "latest",
    "stylelint": "latest",
    "stylelint-config-standard": "39.0.0",
    "time-grunt": "latest"
  }
