It can prevent the application from running properly, as the error indicates that the same handler has been declared multiple times. This can lead to unexpected behavior, as the application may not be able to process the data correctly. Additionally, the application may not be able to access the database, as the error can prevent the database from being accessed. As a result, the application may not be able to function properly, leading to a decrease in user experience.
