If you get the error that says something like the libcrypto is running on unsafe mode and the process is aborted:

brew install openssl
sudo ln -s /opt/homebrew/opt/openssl@1.1/lib/libcrypto.1.1.dylib /usr/local/lib
sudo ln -s /opt/homebrew/opt/openssl@1.1/lib/libssl.1.1.dylib /usr/local/lib
cd /usr/local/lib
sudo ln -s libcrypto.3.dylib libcrypto.dylib
sudo ln -s libssl.3.dylib libssl.dylib
