Hi there, I do not know, there is not enough information here to fix it.
I have a build demonstrator that shows how to get things working from scratch though, and it successfully builds + runs an android app in release mode with react-native-firebase integrated: https://github.com/mikehardy/rnfbdemo/blob/main/make-demo.sh

I would consult that as the definitive guide for exactly how to get react-native-firebase integrated and working.
