React JS npm run start return error SyntaxError: Unexpected token;

Question

I was trying to start react web server with npm start but accidentally it returning

/home/azureuser/react-inventory/node_modules/eslint-webpack-plugin/node_modules/jest-worker/build/index.js:110
  _ending;
         ^

SyntaxError: Unexpected token ;

I thought that this wasn't my fault as it worked fine on my local machine but error on virtual machine is this dependencies problem of eslint-webpack-plugin and I need to submit issue there or this happened because of my machine ?

My Virtual Machine : Microsoft Azure Ubuntu 20.04 LTS Node Version v10.19.0

Full error message produced /home/azureuser/react-inventory/n

ode_modules/eslint-webpack-plugin/node_modules/jest-worker/build/index.js:110
  _ending;
         ^

This problem occurs on older versions of nodejs, like your v10, but not newer versions, like v18. Try upgrading nodejs.
