What happened to all the suggestions in your other thread Updated code, part of it stops? - #12 by Volanaro - Programming Questions - Arduino Forum ? You seem to have ignored most of them in your "latest code".
And if you want to use a library like OneButton you have to do a lot more than just put a #include at the top of the program. For a start you have to look at the examples that come with that library and understand them then put the necessary code into your program.
