webview shows app splashscreen background in select dropdown option

My application base is ionic capacitor. We have created the below setAuthWebViewSettings for opening the webview with url.

@SuppressLint("SetJavaScriptEnabled")
    private void setAuthWebViewSettings(WebView webView) {
      webView.setWebViewClient(new mAuthWebViewClient());

      WebSettings webSettings = mAuthWebView.getSettings();
      webSettings.setJavaScriptEnabled(true);
      webSettings.setSupportZoom(false);

      webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);

      webSettings.setAppCacheEnabled(false);
      webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);
      webSettings.setDatabaseEnabled(true);
      webSettings.setDomStorageEnabled(true);
      
      if (BuildConfig.DEBUG) {
        WebView.setWebContentsDebuggingEnabled(true);
      }
    }

Below is my activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.Enterprise.xxx.mAuthWebView">

    tools:context="com.Enterprise.xxx.mAuthWebView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
 </androidx.coordinatorlayout.widget.CoordinatorLayout>

Below are the issues that I am facing in my webview:

1. Select options shows capacitor default splash screen in the background (screenshot attached below)
2. Date field implemented using date-fns plugin crashes the application

I have tried all the answers in below link, still no luck.
