Where did my scene go?

I was making a 2D game and i wanted to make a level 2, i renamed both. when i renamed the sample scene to level 1 the whole hierarchy dissapeared and the whole level was clear - just blank. Any tips on what could’ve happened? Im a rookie so i don’t know if i am just dumb.

You probably just entered level 2 scene. In the assets, find your level 1 scene and double click it
