We were running into rate-limit issues with Codesandbox. We just increased our limit, so go ahead and try it again and let me know if it works!
It has moved on to the next window and it is spitting out code in the chat window.
Then, it ultimately left up a window which says "Welcome to your new app" and displayed the prompt:
>create a site for creating, editing, and previewing G-code in 3D using blockly.
but I don't see anything beyond that.
Could you hit retry on the message or add a new message? Sorry for the issue
Aren't there logs at your end you could examine? Or why not try this prompt yourself?
I will note that I had a similar result with a far simpler prompt....
Or, let's turn this around --- could you provide a page which documents a successful prompt/project? If you'll let me know the link of that, I'll try it, then once I know this works for my credentials, will try again with the effort I was making.
