react-scripts build failing when updating from 1.x to 3.0.1

I'm trying to migrate react-scripts from my current version (1.1.4) to the latest 3.0.1 for obvious reasons, but I'm having a hell of a time.

Here's my current, build successful package.json

{
  "name": "name",
  "version": "0.1.0",
  "homepage": ".",
  "private": true,
  "dependencies": {
    "ajv": "^6.9.1",
    "axios": "^0.18.0",
    "axios-debug": "0.0.4",
    "date-fns": "^1.30.1",
    "formik": "1.2.0",
    "history": "4.7.2",
    "moment": "2.22.2",
    "localforage": "1.7.3",
    "prettier": "1.14.2",
    "react": "^16.8.1",
    "react-bootstrap": "0.32.4",
    "react-checkbox-group": "4.0.1",
    "react-datetime": "2.15.0",
    "react-dom": "^16.3.2",
    "react-render-debugger": "1.0.2",
    "react-router-dom": "4.3.1",
    "react-scripts": "1.1.4",
    "semantic-ui-css": "^2.4.1",
    "semantic-ui-react": "^0.87.1",
    "styled-components": "^4.2.0",
    "react-router-hash-link": "1.2.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
}

So I'm using npm so running npm install --save --save-exact react-scripts@3.0.1 installs the new react-scripts version, everything is updated correctly. I updated a few other packages that were needed as deps. No security vulnerabilities, everything was clean and installed correctly.

I'm using maven as a build system to build my app, once it tries to execute npm run build it fails on react-scripts build

The debug log is super unhelpful. The only error displayed is /node_modules/.bin/react-scripts: Permission denied

I've tried changing the permissions using chmod +x /node_modules/.bin/react-scripts but no luck.

I've tried deleting node_modules several times and reinstalling the modules using npm ci. Just about any issue I've found on github I've tried.

I'm not sure what else could be wrong.

Using node v11.9.0 and npm 6.5.0

Do I need to update in smaller version increments? I'm really at a loss

EDIT: Something is wrong with npm in my case. Manually updating the package versions in package.json seems to work for now... I need to figure out why npm is broken for me
