npm error : cb() never called, what should I do?

After spending hours on many recommendations that did not work. I finally got npx create-react-app running by doing the following:

1. Uninstall npm by running the following code at your command prompt:

   npm uninstall -g create-react-app
   

2. Increase timeout by changing/adding this line in your .npmrc file:

   timeout=60000;
   prefer-offline=true;
   

   Your .npmrc file can be found in C:\Program Files\nodejs\node_modules\npm (windows)

   Then RESTART your PC

3. Disable your antivirus (as @Antoine said)

4. Run the following at the command prompt

   npm clean cache --force
   npm install create-react-app
   npx create-react-app my-app
   

   where my-app is the name of your project

NOTE: I am not using any proxy.
