On Android, app isn't opened automatically if applicationId is changed

[Geydson]

Description

I'm using expo bare with access to android files. I change applicationId but keep package ID. I run yarn android --appId new.app.id where a different applicationId from the namespace is used but generates a type 3 error and the application does not open.

This does not occur in old versions such as the old project which is on 0.64.4, I am updating to 0.73.4, with this new "namespace" variable, if I leave the "applicationId" different I get the error below.

Steps to reproduce

Run npx react-native init foobar
Open android/app/build.gradle, namespace "com.foobar" change applicationId "com.foobar" to applicationId "com.foo.bar"
Run yarn android --appId com.foo.bar
It throws Error: Couldn't open Android app with activity "com.foo.bar/.MainActivity" on device "Pixel_4_API_34".. and doesn't start app

React Native Version

hey, since you're using Expo please use their command to launch the app.
