Cannot convert undefined or null to object.

After the React Dev Tools update, all production environments crashes with error:

 Cannot convert undefined or null to object

@sptaszek92 Use @fvilers/disable-react-devtools instead

Removing package helps :)

@michalpokojski funny

This issue occurs because the property _renderers not exists any more.
@fvilers/disable-react-devtools replace all properties and methods to prevent the plugin registration process. It can disable the react dev tools v4 successfully and the react app still works.
