Tmux not starting after closing terminal on freeze session

Question

My tmux panes became frozen and I decided to close the terminal because I somehow thought that would fix it. Now, when I run the tmux command in my home directory, tmux's usual green bar doesn't show up at the bottom and it looks like I'm being asked to enter input infinitely.

I'm using tmux 3.1 and there are two tmux-client log files in my home directory, which are shown below. The second log file appeared when I was trying to fix the issue. Also, when I try to open the files I was editing using tmux, I get an error saying that swap files were found for them.

Answer 1

Sounds like the tmux server has hung. Does it work again if you do pkill -WINCH tmux?

If no, you will need to do pkill -9 tmux and restart it.

Do you remember what you were doing when it hung? Can you reproduce?
