feels to me that you installed cross-env globally, and it might break whenever you switch node versions.

i would advise you to have cross-env in the dependency of your project. you can do that by installing cross-env and specify that you would like to save it in your package.json.

try this

npm install --save-dev cross-env

then try again to run your project.
