I just added "@vercel/analytics": "^1.3.1" at the end of my package.json and edited layout.tsx
I ran into the error

Error: Can't parse json file /vercel/path0/package.json: Unexpected token '}', ..."lytics"
  },
  "devD"... is not valid JSON while parsing '{
  "name": "portfolio-new",
  "version"'

It was working just fine before this, I even went back to the original package.json and all of the things i modified and still running into this error
What can be the problem??

First part of my package.json that i think the error is occurring :

{
  "name": "portfolio",
  "version": "1.0.0",
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"
  },

(I use --legacy-peer-deps, --force because i have some old libraries)
But as i said it was working just fine before i modified it and now even the original version is not working
