Hot reload crashes the app

[zatteo]

Describe the bug
Hot reload crashes the app

To Reproduce

• Run the project with yarn start
• Modify some files

Expected behavior
It should not crash the app.

Screenshots

Additional context
2 errors in the console

Uncaught ReferenceError: webpackHotUpdate is not defined

Uncaught Error: On Error is already defined
    setOnError http://localhost:8282/vendors.bundle.js:105556
    App http://localhost:8282/main.bundle.js:3606

Removing --hot in the yarn start command seems to avoid the crash (and hot reload still works)
