Calling makeStyles() stops streamlit from rendering my component

So I have created my own style for the component using { makeStyles } from ‘@material-ui/core/styles’ and everytime I declare a variable to use the style, the renderer stops giving anything. The error is the following:

Following is the code that is causing the error. Note that if you delete “const classes = useStyles();” it will render “Hello”.

import {
  Streamlit,
  StreamlitComponentBase,
  withStreamlitConnection,
} from "streamlit-component-lib"
import React, { ReactNode } from "react"
import { makeStyles } from '@material-ui/core/styles';




const useStyles = makeStyles((theme) => ({
  root: {
    display: 'flex',
    flexWrap: 'wrap',
    minWidth: 300,
    width: '100%',
  },
  image: {
    position: 'relative',
    height: 200,
    [theme.breakpoints.down('xs')]: {
      width: '100% !important', // Overrides inline-style
      height: 100,
    },
    '&:hover, &$focusVisible': {
      zIndex: 1,
      '& $imageBackdrop': {
        opacity: 0.15,
      },
      '& $imageMarked': {
        opacity: 0,
      },
      '& $imageTitle': {
        border: '4px solid currentColor',
      },
    },
  },
  focusVisible: {},
  imageButton: {
    position: 'absolute',
    left: 0,
    right: 0,
    top: 0,
    bottom: 0,
    display: 'flex',
    alignItems: 'center',
    justifyContent: 'center',
    color: theme.palette.common.white,
  },
  imageSrc: {
    position: 'absolute',
    left: 0,
    right: 0,
    top: 0,
    bottom: 0,
    backgroundSize: 'cover',
    backgroundPosition: 'center 40%',
  },
  imageBackdrop: {
    position: 'absolute',
    left: 0,
    right: 0,
    top: 0,
    bottom: 0,
    backgroundColor: theme.palette.common.black,
    opacity: 0.4,
    transition: theme.transitions.create('opacity'),
  },
  imageTitle: {
    position: 'relative',
    padding: `${theme.spacing(2)}px ${theme.spacing(4)}px ${theme.spacing(1) + 6}px`,
  },
  imageMarked: {
    height: 3,
    width: 18,
    backgroundColor: theme.palette.common.white,
    position: 'absolute',
    bottom: -2,
    left: 'calc(50% - 9px)',
    transition: theme.transitions.create('opacity'),
  },
}));

const classes = useStyles();

class ImgButton extends StreamlitComponentBase {
  public render = (): ReactNode => {
    return (
      "Hello"
  );
  }
}

export default withStreamlitConnection(ImgButton)
