StackOverflow strongly prefers "Short, Self Contained, Correct (Compilable), Example"s [sscce.org] that showcase a specific problem.
If you go and paste several files with a few hundred lines of code, you're unlikely to get any help. People will not usually make the effort to set your project up locally (because you likely didn't paste the project configuration), debug it, and send you the diff to the fixed project.
But more importantly, any answer to your question is hard to transfer to problems other people have. It can't be used as a reference or solution repository anymore, because there's so much distraction around the essence of your problem.
