try with hooks - its working for me

ref - https://docs.page/invertase/react-native-google-mobile-ads/displaying-ads-hook

import { useInterstitialAd, TestIds } from 'react-native-google-mobile-ads';

export default function App({ navigation }) {
  const { isLoaded, isClosed, load, show } = useInterstitialAd(TestIds.Interstitial, {
    requestNonPersonalizedAdsOnly: true,
  });

  useEffect(() => {
    // Start loading the interstitial straight away
    load();
  }, [load]);

  useEffect(() => {
    if (isClosed) {
      // Action after the ad is closed
      navigation.navigate('NextScreen');
    }
  }, [isClosed, navigation]);

  return (
    <View>
      <Button
        title="Navigate to next screen"
        onPress={() => {
          if (isLoaded) {
            show();
          } else {
            // No advert ready to show yet
            navigation.navigate('NextScreen');
          }
        }}
      />
    </View>
  );
}
