I get your point, it can be very frustrating if you are overwhelmed by a steep learning curve, and even supposedly simple tasks fail when you start out. When I post a question I only very rarely get an answer. However, I decided it is more likely that people either do not know an answer, or have not the luxury of time to answer. And if someone new starts out, some questions have been answered already, multiple times.
So while you can claim it is a ‘bad community’, it could also mean there is nobody around at the time to answer your question. Perhaps there are 50 posts on an average day, and perhaps you can say something valuable in 30 percent, but this means you direct your attention and time to following the current forum stream.
Also responding to a question can be a unsatisfying experience. So the bottom line is, there are actually not super many experienced devs online - with the time to give support at any given time, and basically, learning Unreal is a grind.
Usually you have to get to the ground of things for yourself. So don’t take it personal if your posts stays unanswered. Reflecting in a post helps you a lot, by just writing down the issue it becomes more clear.
