create-react-app-typescript Error: Cannot find module 'react-dev-utils/workspaceUtils'

Hi there,

Having recently upgrading to [email protected] due to an npm audit which recommended the upgrade, I now get a Cannot find module error when trying to start the server. Testing won't run either.

Audit Results:

Run npm install [email protected] to resolve 80 vulnerabilities

Starting Server:

uuser@ubuntu1:/var/www/html/expired-to-be$ BROWSER=none HTTPS=true npm start

> [email protected] start /var/www/html/expired-to-be
> react-scripts-ts start

module.js:559
    throw err;
    ^

npm ls react-scripts-ts (if you haven’t ejected): 3.0.0
node -v: 9.7.1
npm -v: 6.0.1
Operating system: Ubuntu 16.04 x64

I've looked everywhere for a solution to this. I've gone through all the npm up && npm i and npm i --save-dev react-dev-utils, but can't seem to find any way to get past this error.

Thoughts?

Thanks!

To remove this as a blocker, I downgraded back to "react-scripts-ts": "2.15.1" (alongside "typescript": "^2.8.3"). The 80 vulnerabilities that were previously prevalent did not return, and the 9 that remained did not trigger GitHub's vulnerability alert.

I installed the older version 4.x.x of react-dev-utils manually to resolve the error.
