Answer 1

Removing the directory and trying to reinstall worked for me.

sudo rm -rf /opt/homebrew

Answer 2

Had a similar issue on Mac , I uninstalled it first by typing the command below and I installed Xcode, it worked for me after running the install command again.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
