Warning: React.createElement: type is invalid

[HeisUser]

I am newbie and learner on Remix. Can I know what is this error / bug?

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object.
    at RemixServer (/usr/local/var/www/gitHub/remix-loader/node_modules/@remix-run/react/dist/server.js:48:3)

P.S. Hope you guy can upload latest version tutorial at YouTube and the teaching macterials with list out all the dependencies. Like the Tutorial with Architect.dev, I can't figure out how to install & setup at Remix. So I can't learn further as learner.
