Launch at Login Toggle not working

The launch at login toggle does not work when I package the app for distribution, however it does work when I run the app from XCode. Is there any reason for this? Is there any fix?

I have used this package for years without an issue like this. Try to do some debugging yourself. This may be an issue with your app. There's not much I can do based on the info you have provided.

Okay, I will look at it. I also noticed a significant increase in the app size when adding the package from the package manager. Is there any way to fix this?
