tmux: hangs and do not load, and do not respond to any option command

Question

I have installed tmux from source on my localspace in Fedora. It was working nicely so far. But suddenly can not run it anymore, when run tmux, it just halts. Tried different command options like ls-sessions, none works. Killed all the processes of my user, deleted all the files of tmux and libevnet, and reinstalled them again from scratch. Still same, and tmux command in terminal just freezes without any actual error.
