I tried to compile 28.0.50 --with-native-compilation

this warning came out:

Warning (initialization): An error occurred while loading ‘/Users/niels/.emacs.d/init.el’:

Native compiler error: (lambda (arg0 &optional) (let ((f #'yes-or-no-p)) (funcall f arg0))), Compiling
/Users/niels/.emacs.d/eln-cache/28_0_50-8be1867a/subr--trampoline-7965732d6f722d6e6f2d70_yes_or_no_p_0.eln...

ld: library not found for -lgcc_s.1.1
libgccjit.so: error: error invoking gcc driver

This means your libgccjit installation is broken: it lacks some shared
libraries it needs, at least the one shown, libgcc_s.1.1.so (or maybe
the extension should be .dynlib on macOS?).

the rest of the compilation goes well, however the statement, but emacs
crashes under initialization whenever it tries to evaluate (fset 'yes-or-no-p 'y-or-n-p)......

Yes, of course: it tries to call functions from a missing library.
