i need help everybody

[pierroo]

first questions that come to mind is:

• why are you still using java files for MainApplication?
• RN0.80+ no longer use SoLoader
• New arch is now enabled by default, so your newArchEnabled is probably useless?

Did you use the upgrade helper to know exactly what you must change?
https://react-native-community.github.io/upgrade-helper/?from=0.79.3&to=0.80.1

@pierroo
Thank you, brother. I'll give it a try

• dlopen failed: library "libreact_featureflagsjni.so" not found #50508

There is something wrong with your app update, you haven't followed all the steps of the upgrade helper

@pierroo @cortinico
According to RN0.80.1, the upgrade content has been fully configured and the problem has been solved.

Thanks!
