Running Save Participants... vscode prettier very slow with tailwindcss classes

I'm using TailwindCSS to style my React project. I'm using VSCode with the Prettier addon and I'm getting the "Running Save Participants for ..." alert forever on files that use Tailwind classes. E.g....

<input class="shadow appearance-none border border-red-500 rounded w-full py-2 px-3 text-gray-700 mb-3 leading-tight focus:outline-none focus:shadow-outline" id="password" type="password" placeholder="******************"/>

Is there anyway around this or should I stop using Prettier?
