As suggested by some, I have deleted my node modules folder and then did npm update followed by npm install but still i am getting the same error. Any help would be very much appreciated

Answer 1

I have seen this before. Try deleting your node_modules folder and after that run npm update and then npm install.
If that doesn't work there are a few answers from another forums:
Some windows users said that add System32 to environment variables helped:
Goto Control Panel > System and Security > System > Advanced system settings > Enviroment variables and set a system variable to path C:\Windows\System32\ and restart your System.
Worst case scenario: downgrade react-scripts to 2.1.8 :
npm install react-scripts#2.1.8
