@Kernelpanic
the problem is that in version .82 compiler options were added and it seems to ignore makeline_win.txt
click on C++ Compiler Settings and then in the C++ Linker Flags paste  -Wl,--stack,16777216

I don't have that. But I can think of something: gcc 8.1 is obviously being used, but I already have GCC 11.2.0 installed. Maybe that has an impact. . . 
And now: Thanks for your help, and Good Night. See you later . . .
