Error 127 make HDL project with Cygwin in Windows.

Question

I get an error when I want to make a make command to generate the Refernce Design Project file. 
 I already tried everything what has been described in the "HDL make error 127" Q&A ( RE: HDL make error 127 ) from December 2020. 
 Unfortunately nothing helps any Idea what else I could try?
