Seeing both issues (homebrew path / extreme slowdown) also after fresh install. Unsure if the Homebrew setup is causing the slowdown.
Was able to sort the PATH issue, but still seeing extreme slowdown / hanging. Most actions (clicking prompt streams, entering text in prompt box, etc) delayed by ~2-5 seconds on M1 Mac 16GB. Sluggishness not occurring on other apps (IDEs, Chrome, Claude Desktop app) which are concurrently open. Slowdown making app use unusable atm
