npm create-react-app cannot create an app - reactjs

It creates the files, but after the npm start command this is the error message:
Failed to compile
./src/index.css (./node_modules/css-loader/dist/cjs.js??ref--6-oneOf-3-1!./node_modules/postcss-loader/src??postcss!./src/index.css)
Error: Package exports for '/media/parragi/Új kötet/Web development/react projects/react-playground/node_modules/autoprefixer/node_modules/kleur' do not define a valid './colors' target
The npm version is: 6.12.0
The create-react-app version is: 3.4.1
What should I do with it?

React App Suddenly Failing To Compile - scss unable to import

App was compiling last night when running npm start. This morning it's throwing this error:
Failed to Compile
./src/components/HamButton/styles.scss (./node_modules/css-loader??ref--6-oneOf-5-1!./node_modules/postcss-loader/src??postcss!./node_modules/sass-loader/lib/loader.js??ref--6-oneOf-5-3!./src/components/HamButton/styles.scss)
To import Sass files, you first need to install node-sass.
Run `npm install node-sass` or `yarn add node-sass` inside your workspace.
Running npm install node-sass didn't fix it.
If I comment out all scss imports, app will compile however styles are not applied.
What's causing this and how can I fix it?
Thanks
Node v10.15.3
npm v6.4.1
Apparently my npm install was corrupt so followed these steps: On npm install: Unhandled rejection Error: EACCES: permission denied
Then installed node-sass and it worked.
