Why am I having this problem

I am trying to render my scene but it comes out like this, is anyone knows how to fix this? I need help asap, thanks!

I’ve had this a few times, I never quite know what I do to cause it.

I usually set the render settings back to default to fix it.


Omg it worked. You saved my life, thank you soooooo much :smile::smile::pray::pray:
