I had a similar issue, but unrelated to upgrading. Nonetheless I had a similar fix. Instead of import com.facebook.react.BuildConfig; I had to use import com.projectname.BuildConfig;, where projectname is the name of my project. Hope this helps someone out there.

the diff can b a bit… iffy at times 😅 here’s what we want

https://react-native-community.github.io/upgrade-helper/?from=0.65.1&to=0.69.0-rc.0

to enable

• TurboModules (via MainApplication.java)
• Fabric (via MainActivity.java)

from gradle.properties when

• newArchEnabled=true

if that helps clarify @swrobel
