I think there is no problem with my code, but I run the game and press the space bar to shoot, but the game suddenly closes and gives the following errors:
Traceback (most recent call last):
File “C:UserscemrePycharmProjectsSpaceInvadersmain.py”, line 220, in <module>

File “C:UserscemrePycharmProjectsSpaceInvadersmain.py”, line 43, in init
self.mask = pygame.mask.from_surface(self.img)
TypeError: argument 1 must be pygame.surface.Surface, not None
please help me this is my final project
