App Crashes immediately upon opening picker

[FrankieJLyons]

Hello

Whenever I go to open the date picker the app crashes immediately, I don't get time to read the error that RN throws, but the header says 'Unrecognized font family Material Design Icons'

Here's the relevant code:

import React, {Component} from 'react';
import {Text, View} from 'react-native';
import {TextInput, Button} from 'react-native-paper';
import {DatePickerModal} from 'react-native-paper-dates';
import {KeyboardAwareScrollView} from 'react-native-keyboard-aware-scroll-view';

// Libraries

// Custom Styles
import sScroll from '../assets/styles/sScroll';
import sBackground from '../assets/styles/sBackground';
import sContainer from '../assets/styles/sContainer';
import sImage from '../assets/styles/sImage';
import sText from '../assets/styles/sText';
import sColor from '../assets/styles/sColor';

// Custom Theme
import {TextInputTheme, ButtonTheme} from '../assets/themes/tCustom';

export default class RegisterScreen extends Component {
  constructor(prop) {
    super(prop);

    this.state = {
      firstName: '',
      lastName: '',
      email: '',
      password: '',
      confirm: '',
      dob: '',
      weight: '',
      height: '',
      sex: '',
      showDate: false,
    };
  }

  render() {
    let {
      firstName,
      lastName,
      email,
      password,
      confirm,
      dob,
      weight,
      height,
      sex,
      showDate,
    } = this.state;

    return (
      <KeyboardAwareScrollView

        </View>

            }}>
            Date of Birth
          </Button>
        </View>

        <DatePickerModal
          // locale={'en'} optional, default: automatic

          visible={showDate}

            this.setState({showDate: false});
          }}
          date={undefined}
          onConfirm={params => {
            this.setState({showDate: false, dob: params.date});
          }}
          // validRange={{

      </KeyboardAwareScrollView>
    );
  }
