How to fix crash error with roll a ball beginner tutorial

I just finished the tutorial and until the end everything worked great, but now it is saying I cant run my game after I have built it. It give me an error message that says it has crashed.

Click “Yes” and you should find yourself in a folder where you find a file called “Editor.log”. If not, you should find the file here: “C:\Users\[username]\AppData\Local\Unity\Editor”.
The logfile should contain some hints about why the crash occurs.
