standard assets problem

Im new to unity, and trying to build a simple game not having to do much programming, as i have not learned javascript yet, but i had a chacter, i started devloping my map, and one day I load my project and i can rotate my camera but not move; I took it out and put it back nothing I removed the starter assets and re-imported them, and still nothing. I tried making the 3rd person controller and it will not even allow me to move the camera, but if I make a new project it works. I did nothing but add cubes to my world and give them some crude imaging, so how could I break a chacter?

I don’t what happened in my project but not even standard scenes were playable I made a new project and transferred all my things over and everything’s working
