It was running fine earlier but i got this error after i deleted "registerServiceWorker.js" from my /src and "manifest.json" from /public from my app. I put that file back in the app but no luck! Can you help me go in the right direction please thank you!

does yarn start yield a better result?

if that fails, try running yarn install and then re-run yarn start. Let me know how that goes!

works purrrrfectly!!! thank yoU!!
