Why is there no screen?

Question

So i am away from my laptop for a while, no laptop means no visual studio. So i thought why not create a copy of my project in the playground?
But when i created all of the needed stuff it gave me an error which i normally didn't get.
Everything seems fine and currently all it can do is draw a square on screen and with player input move the square.
Well it CAN , but it doesn't and i don't know why...

Thanks in advance!

Because. The SoloLearn playground is a web-based code editor,It doesn't have access to your local resources.

you run it on your local machine.
