I Sihui,

We provided an iOS and macOS app "client app" which uses an embedded WKWebView as its UI. To reproduce the crash, you require a Windows App to act as the server. During the comminication process between these 2 apps, the UnknownError is triggered on the client app.

The server app can be run on Win10 via Parallels on macOS as per instructions provided.

We have no other way of reproducing the issue. I hope you understand.

great

excellent. this is exactly the kind of advice we wanted. we will verify if this is viable.
