I'm guessing Emacs fails to read the response because visiting that file takes too much time. Try playing with the value of xterm-query-timeout. Or avoid visiting files with such humongously long lines from the command line.

1. Create a large file "foo", e.g. with
echo `seq 10000000` > foo
2. In an xterm, connect to the machine via ssh (AFAIK to introduce
a delay in the transmissions).
3. Type (without <RET>):
/usr/bin/emacs -nw -Q --eval="(setq large-file-warning-threshold
100000000)" foo
4. Type <RET> twice very quickly.
I sometimes get garbage near the beginning of the buffer, after a
blank line (due to <RET>):
11;rgb:0000/0000/00001 2 3 4 5 6 7 8 [...]
I could reproduce this bug in Debian/stable (emacs-nox 1:28.2+1-15),
Debian/unstable (emacs-gtk 1:29.1+1-5), and Android with Termux
(GNU Emacs 29.1).
Without -Q, the bug occurs more easily: no need to be particularly
fast (I get it with <RET> to validate the command + <next> or <end>),
and the file may be smaller.
