Homebrew can't install Watchman: No similarly named formulae found | MacOS Big Sur

Question

Homebrew error screen capture

Anybody know why my Homebrew can't install any packages and keep showing this error?

I've tried to install watchman but homebrew shows me this error, then I tried to install other packages but still, this error shows up. I already tried to install and reinstall homebrew using /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh).

Please help 🙏
