Persistent accessibility issues on 26.4.1

I've installed yabai, but executing any command gives me this error: yabai-msg: failed to connect to socket..

Did the exact same install on a duplicate machine yesterday and had no such trouble. Yabai is turned on for accessibility permissions in Settings. However, running /opt/homebrew/bin/yabai gives me this: yabai: could not access accessibility features! abort.. which triggers a redundant accessibility request that does nothing.

Tried uninstalling and reinstalling—same thing.

I see there's a lot of conversation about this elsewhere on this repo, but all the issues appear to be slightly different from mine or using an earlier macOS. I'm on macOS 26.4.1.
