Not able to compile empty project, expl3-code.tex

[TheOnAndOnlyZenomat]

Hey,
I tried to create a new project with

tectonic -X new tec-test

I didn't change any files, everything is default. When I try to compile that with

tectonic -X build -p

the compilation fails with

note: "version 2" Tectonic command-line interface activated
note: generating format "latex"
(texput (tectonic-format-latex.tex (xelatex.ini (latex.ltx (texsys.cfg)
./texsys.aux found


\@currdir set to: ./.


Assuming \openin and \input 
have the same search path.
