"Iterator == end" in Editor and Scene is Empty

Accidenlty, I had a crash in my Computer. After I turned on my PC and Opened up Unity, It showed me a dialogue box regarding layouts. I set them to default. After that what i see when loading the scene is that in console there is an error “iterator == end” and scene is empty, nothing in heirarchy (even not Main Camera). Any way to solve it?

hi;
see if unity didnt create another library or temp floder in your asset folder by mistake;
some times it happense and u have to delete them ;
