React Styled Components: ReferenceError: Cannot access before initialization

SharedButton is the base style of a button inside my app, and it is shared across components. I am trying to override the styles of this button inside MyComponent.

I am getting the following error when myComponent mounts: ReferenceError: Cannot access 'SharedButton' before initialization.

Note that If I don't import SharedButton from a different file, ie. if I define it inside "MyComponent", I don't get the error. How can I solve this issue?

shared.ts

import styled from "styled-components";

export const SharedButton = styled.button`
  border: 1px solid red;
  color: #1c101e;
  font-size: 14px;
`;

myComponent.ts

import { SharedButton } from "./shared";
import styled from "styled-components";

const MyComponentButton = styled(SharedButton)`
  float: right;
`;

const MyComponent = () => {
   return <MyComponentButton> TEST </MyComponentButton>
}

Try placing the MyComponentButton style in shared.ts and export to the myComponent.ts. sandbox examples

shared.ts

import styled from "styled-components";

export const SharedButton = styled.button`
  border: 1px solid red;
  color: #1c101e;
  font-size: 14px;
`;

export const MyComponentButton = styled(SharedButton)`
  float: right;
`;

myComponent.ts

import { MyComponentButton } from "./shared";

const MyComponent = () => {
   return <MyComponentButton> TEST </MyComponentButton>
}

The second approach, put some props in styled-components

shared.ts

import styled, { css } from "styled-components";

export const SharedButton = styled.button`
  border: 1px solid red;
  color: #1c101e;
  font-size: 14px;
  ${({ floatRight }) =>
    floatRight &&
    css`
      float: left;
    `}
`;

myComponent.ts

import { SharedButton } from "./shared";
    
export const MyComponent = () => {
  return <SharedButton floatRight> TEST </SharedButton>;
};
