Hi, I have the same problem and it did not execute perfectly. Although it said "Process finished with exit code 0", it didn't actually print "Hello World". So it says that there are no errors in the code, but it doesn't output what you asked it to show.
My problem occures when I try to run my code to draw a chessboard. It says "Process finished with exit code 0", but it doesn't display my chessboard.
