You are loading pdfx too late and so it can't set the pdfversion
itself, it will then error if the current value is different to the
one it wants to use. 

In your case you can probably avoid the error by loading
\usepackage{luatex85} before pdfx, but a better solution is to move
pdfx to some earlier place in the preamble (before tikz probably).
