It worked !!!! Adding this parameter "--generate-entitlement-der" does the trick. My applications code directory v is 20400 and it is working on iOS 15.0.

No problem with WKWebView. But the our migration from UIWebView to WKWebView is still in progress. So is there is any work around to resolve the issue in UIWebView? And any deadline announced by Apple on the WKWebView migration?
