Netlify Deploy

[OlaoyeVic]

I tried deploying my app with netlify, but after the deployment it is not displaying anything; more like a blank page. Please can you help with any assistance?
Here's a link to my codesandbox;

The sandbox link doesn't work, but FYI, you can View Logs when deploying and look for errors.
