Hello there!

I'm currently working on a project for my resumé that is supposed to be a GUI based login system. It's been going pretty well until now. I want to open a new window for the LoggedIn class after you have successfully logged in but it doesn't open a new window and I don't for the life of me get why.

Any help as well suggestions on improvements is highly appreciated, thank you and have a great day!
