fish 3.5 failing to start under tmux #9019
Description
User "alexpw" reports on Hacker News:
This killed all shell interaction within my tmux setup, somehow, and I had to downgrade in osx/brew [1] back to v3.4.1 [2]. I'm still wondering what part of my (probably outdated) tmux config caused it, but the most suspicious part is the run-shell/if-shell stuff.
They shared their .tmux.conf. This issue is to track investigating it.
