I was getting the same error when running a script that automatically configures tmux workspaces and then attaches them.

However, when I ran the tmux command by itself, I got a more useful error. It told me that a few lines of my ~/.tmux.conf file were causing errors. They're out of date, I guess.

I commented out these lines and now everything works. Maybe that'll work for you, too?
