Hi @eskimo, we also have such crashes, I have sent them in FB13169200

We see zero crashes starting from 22 of September (iOS 17.0.1 release date?), previously it was 5–10 crashes per day. We will continue to watch.

For me downgrading TLS to 1.2 fixes the issue: let configuration = URLSessionConfiguration.default #if targetEnvironment(simulator) configuration.tlsMaximumSupportedProtocolVersion = .TLSv12 #endif let session = URLSession(configuration: configuration)
