Try adding a .env file to your root project directory (where you have package.json and node_modules). Then inside .env, add CHOKIDAR_USEPOLLING=true. This just worked for me when I was having issues with hot reloading not working. Apparently the "watcher" requires this setting when working with a VM (like WSL). I found this recommended in the top answer here: React create app hot reload is not always working on linux
