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)

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.

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