Have you noticed the error message in your output?

Database Emulator has exited because java is not installed,
you can install it from https://openjdk.java.net/install/

I would recommend following the instructions to install java. Also check the requirements here https://firebase.google.com/docs/emulator-suite/install_and_configure
