OP seems to be on windows and I am on (currently) ubuntu so perhaps now very

C-c stopped working -- emacs, shell, everywhere.
Followed from some hacking to setup keyboard -- compose key etc
Dont remember exactly what I did... Deleted some file somewhere ~/.config
/something-or-other and it started working
