Can't load Video from local assets | EXPO-AV

I don’t know because of what, but I can’t take videos from my local assets

Here’s the code:

import * as React from "react";
import {
  Image,
  Platform,
  StyleSheet,
  Text,
  TouchableOpacity,
  StatusBar,
  Dimensions,
  TextInput,
  KeyboardAvoidingView,
  AsyncStorage,
  View,
  FlatList,
  RefreshControl,
} from "react-native";
import { ScrollView } from "react-native-gesture-handler";
import * as WebBrowser from "expo-web-browser";
import * as Permissions from "expo-permissions";
import { Overlay } from "react-native-elements";
import { Notifications } from "expo";
import ShimmerPlaceHolder from "react-native-shimmer-placeholder";
import { MonoText } from "../components/StyledText";
import { AdMobInterstitial } from "expo-ads-admob";
import { copilot, walkthroughable, CopilotStep } from "react-native-copilot";
import { Video } from "expo-av";
import { Asset } from "expo-asset";

export default class HomeScreen extends React.Component {
  constructor() {
    super();
    this.state = {};
  }

  componentDidMount = async () => {
    const { state, navigate } = this.props.navigation;
    const { navigation } = this.props;
  };

  render() {
    return (
      <View style={styles.container}>
        <View
          style={{
            height: height,
            width: width,
            justifyContent: "center",
            alignItems: "center",
            backgroundColor: "black",
          }}
        >
          <Video
            source={require("../assets/images/vids/as.mp4")}
            rate={1.0}
            volume={1.0}
            isMuted={false}
            resizeMode="contain"
            shouldPlay
            useNativeControls
            isLooping
            style={{ width: width, height: height }}
          />
        </View>
      </View>
    );
  }
}

HomeScreen.navigationOptions = {
  header: null,
};

export const { width, height } = Dimensions.get("window");

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#fff",
  },
});
