App only renders background and doesn't render the body - TypeErro: useRef is not a function

[Mushorwell]

When I load this react todo list, only the background is rendered. In the console there's an uncaught error:

Uncaught TypeError: useRef is not a function

Also the following message after the uncaught error:
