It appears that you are using old version of node 14.x.. You should do following would help application up on npm start ,

• Remove node_module folder
• Remove package.lock.json file.
• Check node version in you machine execute command node -v
• If it is not 16.xx execute nvm use 16.15.1
• Execute npm install
• Execute npm start
