Description of the problem

I tried to run codesandbox-client lollcaly, and I found several problems:

1. I use nodejs 16.13.1, but the lru-cache 10.0.1 need. node version >= 16.14, so I reinstall nodejs 16.14.2 .
2. after yarn install; yarn start, I open http://localhost:3000 with browser, but I found 404 error for. service-worker.js. and manifest.json . these files are under 'www' folder, I'm not sure why these files can't be find
3. I create a. sandbox of. 'HTML&CSS', after redirect to this sandbox, the content is 'Whoops, page not found We can’t seem to find the page you’re looking for'.
