Answer 1

In WSL2 work for me, "If the project runs inside a virtual machine such as (a Vagrant provisioned) VirtualBox, create an .env file in your project directory if it doesn’t exist, and add CHOKIDAR_USEPOLLING=true to it. This ensures that the next time you run npm start, the watcher uses the polling mode, as necessary inside a VM."

Or just run: $ CHOKIDAR_USEPOLLING=true npm start
