Plugin "react" was conflicted between "package.json..." and "BaseConfig..."

I tried to start my react app by starting my server - npm start
But I kept on encountering the error above on my browser.

Here is why:

I was running my project on the right folder, but canonically the wrong one. (The capitalization of the path to the folder should be correctly capitalized as it is in your directories)

For example
D:/dev/projects/react-app-1

D:/Dev/Projects/React-app-1

The above paths are not identical.
