Issues with imported .css ("Failed to load the app. Try reloading it.")

In aistudio apps builder, whenever I try to use a package that make use of css (e.g.
“react-image-crop”: “https://aistudiocdn.com/react-image-crop@^11.0.10”
that need an
import 'react-image-crop/dist/ReactCrop.css';
the preview is broken with the error Failed to load the app. Try reloading it.

removing the import statement of the .css it works (but of course it doesn’t uses the css)

Also it seems there is no working support for local .css files in tsx files, can you support it please? (or give workarounds beside "include your stiles straight into your .html file or similar)

Thanks
