try changing “start”: "tsc && concurrently "npm run tsc:w" "npm run lite" " to: “start”: "concurrently "npm run tsc:w" "npm run lite" " in your package.json file. Worked for me

This is nodejs problem - not lite-server. Try to reinstall all packages by deleting node_modules folder and then run command ‘npm install’
