I am using MUI v5 and have a simple FormControl as below I know that the property fullWidth is valid as outlined in the documentation.

import React, { PropsWithChildren } from 'react'
import { Theme } from '@mui/material/styles'
import styled from '@mui/material/styles/styled'
import InputLabel from '@mui/material/InputLabel'
import MenuItem from '@mui/material/MenuItem'
import MuiFormControl from '@mui/material/FormControl'

interface SelectProps extends MuiSelectProps {
  id: string
  label?: string
  options?: { text: string; option: string }[]
}

const FormControl: React.FC<{ theme: Theme }> = styled(MuiFormControl)(({ theme }) => ({
  color: theme.palette.nav.links,
  borderRadius: 30,
  width: 180,
}))

export const Select = ({ label, id, children, options }: PropsWithChildren<SelectProps>) => {
  return (
    <FormControl fullWidth hiddenLabel>
        <InputLabel>
          {label}
        </InputLabel>
    </FormControl>
  )
}
