This issue is not because of Reactjs it's because your system doesn't know the path to your system32. Please follow the below instruction to fix this

Goto > Control Panel\System and Security\System\Advance system setting\Enviroment variable and set system variables path C:\Windows\System32\ variable and restart your System.

One more options is to downgrade your react-scripts in the packge.json to 2.1.8=> keep this as your last option.

Happy Coding.

Try to downgrade the react-scripts module to version 2.1.8 instead of 3
