Could not determine Node.js install directory

As error says Cannot find module 'emoji-regex' so I went to 'C:\Program Files\nodejs\node_modules\npm\node_modules\emoji-regex' to check is there any problem with emoji-regex npm module but when I clicked on that folder it showed an error as file or folder is corrupted or unreadable.

Now, I want my react app to run uninterruptedly but not able to do that, so can anyone plz help me in resolving this error?

The error itself says that you have added a dependency in package.json file, but it's not found in node_module folder. So, simply do npm i and your problem will be solved.
