I wanted to run 'brew update' but run 'brew upgrade'.
After that, my tmux stop working on some functionalities.
For example, I cannot split windows. I have already tried using shortcut (Prefix-%), terminal command (tmux split-window), or tmux command (Prefix-:split-window). Sometimes the terminal divides the window for a fraction of time and then the new pane fades out. Sometimes nothing happens.
If tmux is detached, I can attach with tmux attach but some other commands are not working. For example, if I run tmux new-session -As "foo", it returns the string [exit] and if I inspect the return (echo $?), it returns 0.
I have already tried to run tmux without any configuration in case my tmux.conf have some problems. But when I run tmux -f /dev/null, it returns the string [exit] and if I inspect the return (echo $?), it returns 0.
The problem is that I am not sure if the problem is with tmux itself (it was upgraded to 3.2a - and I did not remember which version it was before) or if the problem is with another program or with the fact I am running with Mac M1 processor, that causes me problems in a bunch of situations.
I have already tried to downgrade tmux but there are not many materials on how to do that I the ones that I tried did not work. So I give up, especially because I was not sure if this would solve the problem.
In summary, I need some help at least to know how to best debug the problem.
Thanks!
