No, that's very very improbable. biber and latexmk are running so
perl is fine. 

I also doubt that biber is the problem: Your log shows that biber
gives only warnings. But you wrote "I have to press a few times with
xelatex". This sounds as if the xelatex run gives errors and that
you are ignoring them. In this case it is easy to reproduce your
problem.

I can get your error message (Latexmk: Errors, so I did not complete
making targets) with a simple document like this:

\documentclass{article}
\begin{document}
\xy
\end{document}
  

So check at first the log-file of the xelatex run.
