Is it "emacs -Q -nw" or "emacs -Q -nw ~/.config/emacs/init.el", as you
reported in your original report?  If the latter, we need to take a
closer look at your init.el: can you find which part of it triggers
this, and post that part?

If "emacs -nw -Q" already triggers the error, please tell what is the
terminal file from lisp/term/ that Emacs loads on your system.  Also,
please show the output of evaluating the following variables in
*scratch*:

 features
 load-history

(Evaluating them will by default show ellipsis: type RET on that
ellipsis to show the full value.)
