Hi. Normally in previous projects, I've installed the 'styled-components' dependency like so:

import styled from "styled-components";

const CustomInputStyled = styled

import styled from "styled-components";

The tags reappear:

yarn create react-app my-app --template typescript

Here is the error message:
