Troubleshooting

com.apple.universalaccess

If you get the following error:

could not write domain com.apple.universalaccess

Open System Preferences -> Security & Privacy -> Full Disk Access. Find "Terminal" (or whatever terminal emulator you're using) and check the box next to it. Then retry the darwin-rebuild switch command.

Brew bundle always removing the same cask

If every build removes the same cask, even if it isn't found, make sure it doesn't come up in brew list. If it does, there may be a .metadata file left in /opt/homebrew/Caskroom/.... Remove that file, and the build should no longer always remove the same cask.
