Nopes, it's not fixed in MACOS 12.5.1.

Yes we need to call this function only once in the app. Then it swizzle the original method. It must be called before the initialisation of WKWebView. FYI In start crash is random. We tried many fixes. Last week i am able to know the exact steps. Type in any UITextField that has autocorrectiontype set to default or secureTextFiled or a textfield with numberpad Now directly go to the view that contains WKWebView with textarea. Now Click on the text area to add text. It's crash.
