You may have encountered this issue because you're compiling the application using Qt5. I apologize for the oversight; this codebase has not been tested for compatibility with Qt5. It is designed to work exclusively with Qt6. I will promptly address this issue with a quick fix on this branch.

Finally, I realized that the function screen() was introduced in Qt version 5.14. Unfortunately, this app does not support Qt versions below 5.15. I will include this requirement for building the source in the document later.
