We are encountering a crash that occurs more frequently on iOS 18 beta 3 and beta 4. The crash happens suddenly after startup and does not provide a detailed code stack trace. Additionally, we have noticed that WebKit has a new version with fixes available. Could you let us know when this update will be released?
webkit has fix this crash: https://github.com/WebKit/WebKit/commit/03200a8c08079e188c3de7a97109a51202cc6c64
