macOS app store app - LoginItem not launching after login

Hello,

My app has a helper application to register with launched using-

SMLoginItemSetEnabled

When both the main app and helper app are signed with dev cert, the helper app is launched/called as soon as you login, but a prod singed apps do not work as expected. In this case, the helper app is not auto launchd upon login.

This behavior is not seen in macOS 11.0/11.1. Here the prod signed helper app is launched as expected upon login.

Upon further investigation, I found the following log entries in system.log file

Feb 11 00:38:33 MacBook-Pro com.apple.xpc.launchd[1] (com.company.HelperApp[2121]): LaunchServices returned a bundle URL that does not match with the LoginItem's known association.

Feb 11 00:38:33 MacBook-Pro com.apple.xpc.launchd[1] (com.company.HelperApp[2121]): Service exited with abnormal code: 78

Feb 11 00:38:33 MacBook-Pro com.apple.xpc.launchd[1] (com.company.HelperApp): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.

What does the log mean and how can I get the prod signed builds to work as expected?
