It would be easier for us if you had put events that pertained to a particular entity inside their own class. For example a players movements in a players class, aliens effects in the aliens class, etc. Then everything you need to know about the alien would be in the alien class.

based on this

            if ai_settings.alien_hp <=0:
                 
                stats.score += ai_settings.alien_points * len(aliens)
                sb.prep_score()
                check_high_score(stats, sb)
                 
            else:
                sb.prep_score()
                check_high_score(stats, sb)

It looks like the only thing that occurs when an alien is 0 or less is shown above in the code snippet...

Which none of those seem to remove the entity from the game. Or at least i couldnt find where you remove the entity from the game in scanning the code.

def create_alien(ai_settings, screen, aliens, alien_number, row_number):
    """create an alien and place it in a row"""
    alien = Alien(ai_settings, screen)
    alien_width = alien.rect.width
    alien.x = alien_width + 2 * alien_width * alien_number
    alien.rect.x = alien.x
    alien.rect.y = alien.rect.height + 2 * alien.rect.height * row_number
    aliens.add(alien)

You create aliens, and add them to this group, but i dont see you removing them from the group at all except for during check_play_button (which is irrelevant to the problem)
