Tried different solutions, but there is this issue during npm install. I've deleted the package-lock file and tried. The --force or --legacy-peer-deps option didn't help either.
npm WARN deprecated core-js@2.6.12: core-js@<3.4 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.

You can try these steps by installing node-sass based on your node version
rm -rf node_modules package-lock.json
npm install --saveDev node-sass@6.0.1
npm install
Edit
Due to deprecation, changing node-sass to sass should resolve this
