Module not found. “@babel/runtime/helpers/builtin/classCallCheck” can't be resolved

Question

I have cloned a repo and did npm i . But as I ran it I was getting the above mentioned error on my console. So I tried a solution from this question and the error disappeared. But now the problem is that my app isn't loading I'm getting a blank page without any errors. I then removed the @babel/runtime dependecy. Here is my package.json:
