new install of Miktex and luatex does no longer compile

I did a fresh install of my Windows and reinstalled MikTex and now I can no longer compile any document using luatex. This problem seems similar to this Lualatex produces no output (MiKTeX) and this TexLive 2019 lualatex doesn't compile document and this LuaLaTeX does not compile after upgrade to TeX Live 2020 problem, but none of the solutions there helped me.

documentclass[10pt, a4paper]{paper}

begin{document} % this command starts the document
test 
end{document} % end the document

If I compile this in pdftex or xelatex, there is no problem, but in lualex I get (after like a 2 minute wait):

This is LuaHBTeX, Version 1.13.0 (MiKTeX 21.2)
 restricted system commands enabled.

Sorry, but luahblatex did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

Sorry, but "MiKTeX Compiler Driver" did not succeed.
