Created attachment 458080 [details] A crash that illustrates this bug. https://bugs.webkit.org/show_bug.cgi?id=237452 adds a call to -[ASCAgentProxy cancelCurrentRequest] in WebAuthenticatorCoordinatorProxy's destructor and appears to have shipped with the Safari 15.5 bundled with macOS 12.4 Beta (21F5058e). However, this method does not exist (or is not exposed), at least in the non-internal build. This causes Safari to crash when navigation occurs after a WebAuthn operation, such as my employer's VPN login flow.

Could you please check with the latest beta? This got fixed outside WebKit.
I can reproduce this on macOS 12.4 Beta (21F5063e), which is the latest version available to me.
Re-opening.
We double-checked, and the relevant fix has not yet been merged with the beta build though it will be part of the release.
This change has finally shipped.
