Simply because ctrlc() assumes to have a woeking console device, and
devices support depends on code which is not available before
relocation to RAM.

You reported that ctrlc() was _not_ working - which is to be expected,
as I already explained to you.

You have someting that seems to work for you, but this does not mean
that it works on other boards, on other processors or on other
architectures.

I don't intend to dicuss this in more and more iterations. You know my
opinion.
