App crash with new Architecture

[margotbignon]

What happened?

Hi,

I recently upgraded my application to React Native 77 and am trying to use the new architecture.
I installed RNN 8.4.0 and the build works, but when I launch the app, it crashes with this error:

FATAL EXCEPTION: main
Process: com.xxx.xxx.qa, PID: 5116
java.lang.RuntimeException: Unable to create application com.xxx.MainApplication: java.lang.NullPointerException: Attempt to invoke interface method ‘com.facebook.react.devsupport.interfaces.DevSupportManager com.facebook.react.ReactHost.getDevSupportManager()’ on a null object reference

at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2416)
at android.os.Handler.dispatchMessage(Handler.java:107)

Do you know how I can fix this?

Thanks a lot !
