Compiled the MailKit sample app (https://developer.apple.com/documentation/mailkit/build_mail_app_extensions) and dropped it into my Applications folder. This Mac hasn't used Mail up until now but I enabled it Mail > Settings > Extensions > "SampleMailExtensions" then the app would crash after a few seconds. App doesn't crash if SampleMailExtensions is disabled. Crashed Thread: 7 Dispatch queue: MCTaskHandler queue" Someone else has a similar on-startup crash with the sample MailKit Mail Extension enabled in Mail. His Mail.app crashes on startup. His seems to crash in "Dispatch queue: IMAPNetworkTaskHandler queue (QOS: BACKGROUND)" which is slightly different than the crash I reported above. Likely related to MEMessageSecurityHandler? macOS Ventura 13.6, Sonoma 14.0 beta 6
