Thanks for the help! - it is so much work...
I'm happy that I finally found the errors when building Windows.
It was banal, they were file names from my src.
I hardly ever do anything in Windows.
I started with C in the mid-90s with Mingw.
But when Linux came along, I didn't do anything in Windows with capital letters anymore.

attached is a screenshot of the color dialogs in scripting (acad_colordlg, acad_truecolordlg)
