Android Webview Not Working After Updating Android System webview

Making calls to webpage via javascript interface stopped working after updating Android System webview to v- 92.0.4515.105. This issue is mostly on Samsung devices, running Android 11. Works perfectly fine on other devices.

This is my settings:

    // attach the interface 
 webView.addJavascriptInterface(this, "Android");
    //setup webview settings
        private void setupWebViewClients() {
            this.webView.getSettings().setJavaScriptEnabled(true);
            this.webView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
            this.webView.getSettings().setDomStorageEnabled(true);
            if (Build.VERSION.SDK_INT >= 19) {
                this.webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
                this.webView.getSettings().setAppCacheEnabled(true);
            }
            else {
                this.webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
            }
            this.webView.setWebChromeClient(new WebChromeClient() {
                public void onProgressChanged(WebView view, int progress) {
                //App logic
            });
            this.webView.setWebViewClient(new WebViewClient() {
                public void onPageStarted(WebView view, String url, Bitmap favicon) {
                }
    
                public boolean shouldOverrideUrlLoading(WebView view, String url) {
                    //App logic
                }
    
                public void onPageFinished(WebView view, String url) {
                    //App logic
                }
    
                public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
                }
    
            });
        }

And I am calling functions this way:

this.webView.loadUrl("javascript:updateGps('dumny',dummy')";

Is there any other settings introduced in Android 11 that I am not aware of? Or it's the bug in Google's Android system webview? Please help me out if there's any work around. Thank you.
