Symbols are a "new" javascript concept that isn't supported in IE11.

You'll need to eject and change your target in your compiler so it transpires this to something IE11 can interpret.

Answer 2

React 18 does not support Internet Explorer. Drop back to React 17 if you need to support that (note that IE is end-of-life though).

Even with React 17, you'll likely need polyfills, such as react-app-polyfill .
