The TTY freezes after “Ctrl-A” hotkey and “s” pressing with GNU screen

I would like to split a window horizontally.
When I type screen and then press Ctrl-A and press s, the TTY freezes.

ctrl-a s in screen sends the underlying terminal a ctrl-s which causes it to stop. You can resume with ctrl-a q.

If you want split screen, you want ctrl-a S with a capital "S" not a lowercase "s".

No. TTY freezes, but terminal on GNOME does not. And how does TTY freeze: open another TTY and login, find the PID of that TTY and kill it, and check the process has been killed. But that TTY still freezes.

Yes, I know. ctrl-q should fix that, or follow directions as in the answer. Or type ctrl-a ? and look at the help screen in screen. You will find _S_ next to _split_ and _s_ next to _xoff_. See https://en.wikipedia.org/wiki/xoff

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
