Whenever I press the play button Unity crashes, when I reload it Unity won't reload my GameObjects

Ok, so far I only have a sphere and a plane and whenever I press play Unity crashes… I don’t even have any code yet. When I reload Unity the two game object have disappeared. I know this may be kind of a noobish question but I’m new to Unity

ok so i was being dumb and all I had to do was click on the Scene it was saved on. But I still need to fix the error of the program crashing
