Hello, I'm new to this framework, and as a student, I've been assigned the task of creating a login/registration form. Initially, everything was working well, from registering an account to logging in. However, I encountered an issue when I opened it from my main page, which has two buttons: one for login and one for registration. Whenever I click either of these buttons and then click anywhere on the newly opened form, the program abruptly terminates. I'm wondering if this problem is due to a software issue.
