Above is the code for my GUI. If the code of any other classes such as the LibraryUser class, library class, book class etc is needed I can provide it. Everytime I try to run the GUI, my IDE gets stuck loading at 50% and stays like that. However, it returns no compilation errors. What’s wrong with it?

Tried asking GPT 4o and Google Gemini but they didnt really help.
