[Solved] Compilation Failed

For some reason I can't upload my sketch to my arduino. I'm using an arduino uno.
Here's the sketch link: Arduino Cloud

Hi @logant09,
I can compile and upload your sketch (I see a bareminimum sketch). What kind of error do you have? Send us any log from the compilation output or screenshot

It verifies fine but when I click upload it says "compilation failed." I have my arduino plugged in with a usb cable. I don't know where a log from the compilation output would be.

I just re-typed the code in a new sketch and everything is working now. For some reason on the first one there was nothing in the log on the bottom. It uploaded fine.
