I openly advise my students to stay away from posting questions on StackOverflow and ask for help among their peers and teachers. At least until they're able to clearly grasp what the "Minimal Complete Verifiable Example" is, how to minimize code, and how to google problems with slight variations, which are not easy skills. It's not to say that StackOverflow is generally toxic. It is, though, unusable by beginners, and it's mostly by design. And I don't think there is a good way to communicate this to a beginner whose question has been just closed because it lacks details.
