Why does my code keep crashing when trying to setup my collide system?

So I'm making a small game with painter for a school final and I got to where my collision part and for some reason, it just crashes. Also, I'm using visual studio code. I was also wondering if there was a way to condense most of this code. I feel as though I am doing it the longest way possible. Any help would be appreciated, thanks!

#make field border
field.shape("square")
field.color("green")
field.shapesize(100)

#line setup
