Your images are unreadable. Don't post pictures of text. Just copy and paste the text.
Don't you think people might need to see the code that is causing the problem? You don't even say if they are .ino files or .h or .cpp files or whatever.
On the other hand, I can't see myself reading 1100 lines of code or 6 files.
When did you first discover this problem? I doubt if you wrote all 1100 lines of code without testing any of it. Can you replicate the problem with a short program?
My very wild guess is that there is one or more strange characters (maybe some unicode has crept in) in one of your files.
