Post app update our extension version is replaced with the new version. However occasionally maybe around 20% of the time The XPC connection we have for communication between the app and extension will not work. We have reconnection retry logic as well as tried stop and starting the extension but it appears once its broken its broken and all that fixes it is a machine restart. This is obviously not ideal. I have noticed a few other forums talking about the same or similar problem. https://developer.apple.com/forums/thread/728063 https://developer.apple.com/forums/thread/779395 https://developer.apple.com/forums/thread/742992 When we run on a broken upgrade cycle `sudo launchctl print system/NetworkExtension.com.company.example.app.filter.5.5.0.2248 ` We notice that endpoints is missing from the log. However if we run the same command in terminal for a working upgrade cycle endpoints = {} exist. Therefore for some reason our xpc isn't actually getting registered.

After an app update replaces our extension with the new version, the XPC connection between the app and the extension fails to work roughly 20% of the time. Once it's broken, it stays broken — our reconnect/retry logic doesn't recover it, stopping and starting the extension doesn't recover it, and the only thing that fixes it is a full machine restart. This obviously isn't ideal. I've seen a few other threads describing the same or a very similar issue: https://developer.apple.com/forums/thread/728063 https://developer.apple.com/forums/thread/779395 https://developer.apple.com/forums/thread/742992 On a broken upgrade cycle, when we run: sudo launchctl print system/NetworkExtension.com.company.example.app.filter.5.5.0.2248 the endpoints entry is missing from the output entirely. On a working upgrade cycle, the same command shows endpoints = {} is present. So it looks like our XPC service isn't actually getting registered with launchd in the broken case. We've tried various changes to our connection logic, but nothing prevents the issue — random upgrades still end up broken with no obvious cause. Is there a known way to recover the XPC registration without requiring a machine restart?
