You have used the name bullet several times, but for different things. At the beginning it is a pygame.Surface object, but after adding the 1st bullet,

bullet = Bullet(player.rect.centerx, player.rect.centery, player.direction, bullerRect)

it reference a Bullet object. Rename the variables.

Use the name bullet_surf for the image that represents the bullet:

bullet_surf = pygame.image.load(...)

class Bullet(pygame.sprite.Sprite):
    def __init__(self, x, y, direction, rect):
        pygame.sprite.Sprite.__init__(self)
        self.speed = 10
        
        self.image = bullet_surf

To fire a bullet with the space bar see:
