Calling Present on View Fails with modally active controller error - ios

Question

When calling present on a hamburger menu, it succeeds on the first load but fails on the second.
Once the app launches you log in. It then calls the listener to perform actions after log in. You can click the burger menu on the left and it works. Now, if you log out, log back in and then hit the burger menu again, it throws the error Application tried to present modally an active controller HomePageViewController. It seems as if something was loaded correctly when the app first loads and it's trying to do it again which is causing to fail. I can't figure out what. Any help would be appreciated here. I've included AppDelegate.swift and AppController.swift which both are relevant here.

present(SideMenuManager.default.menuLeftNavigationController!, animated: true, completion: nil)
