Research direction

Investigate the crash on program close. Start by examining the app's lifecycle callbacks in the main.dart file and any custom window close handlers. Look for unhandled exceptions or errors in platform specific code (e.g., Windows or Linux). The issue mentions clicking the close button, so check for any event listeners on the window close action. Since it's a Flutter app, may need to inspect the engine layer or native runners.
