+[UIView setAnimationsEnabled:] being called from a background thread. Performing any operation from a background thread on UIView or a subclass is not supported and may result in unexpected and insidious behavior. trace=(....)

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(nonnull WKNavigationAction *)navigationAction decisionHandler:(nonnull void (^)(WKNavigationActionPolicy))decisionHandler {
    dispatch_async(dispatch_get_main_queue(), ^{

            if (navigationAction.navigationType == WKNavigationTypeLinkActivated) {
                if (navigationAction.request.URL) {
                    if (![navigationAction.request.URL.resourceSpecifier containsString:@"ex path"]) {

                            //------>
                            UIApplication *application = [UIApplication sharedApplication];
                            [application openURL:navigationAction.request.URL options:@{} completionHandler:nil];
                            decisionHandler(WKNavigationActionPolicyCancel);
                        }else{
                        }
                    } else {
                        decisionHandler(WKNavigationActionPolicyAllow);
                    }
                }
            }
        
            else if  (navigationAction.request.URL && [[NSString stringWithFormat:@"%@",navigationAction.request.URL] rangeOfString:@"disconnectChat"].location != NSNotFound ){
                decisionHandler(WKNavigationActionPolicyAllow);
             
                [UIView animateWithDuration:0.5 animations:^{
                   self->_thankYouView.hidden =  NO ;
                } completion:^(BOOL finished) {
                }];
            }
            else {
                //------>
                    decisionHandler(WKNavigationActionPolicyAllow);
            }
    });
    
}

Try use this

- (void) webView:(WKWebView *)webView
     requestMediaCapturePermissionForOrigin:(WKSecurityOrigin *)origin
     initiatedByFrame:(WKFrameInfo *)frame type:(WKMediaCaptureType)type
     decisionHandler:(void (^)(WKPermissionDecision decision))decisionHandlerii
     API_AVAILABLE(ios(15.0))
{
    decisionHandler(WKPermissionDecisionGrant);
 
}
