Homebrew on XCode 13.4 failing with auto-update disabled

Today our XCode 13.4 jobs started failing on our brew bundle step. We are able to resolve the issue by removing the recommended HOMEBREW_NO_AUTO_UPDATE: 1 environment variable (Using the macOS execution environment - CircleCI) but this significantly increases the runtime of our jobs.

Is there any way to resolve this without needing to auto-update every run?

Ah, cool. Well homebrew is basically broken on older images :smiley: we had to just rip it out entirely and manage some package installations manually instead.
