Not the same exact error, but similar issue.
in my case, I migrated from unreal 4.27 to 5.3, and in engine 4.27, I had to manually add this line to project settings under extra tags for game activity due to some new play store policy:
android:exported=“true”
After migrating, seems like UE 5.3 adds this tag itself, so adding it manually made it duplicate. Simply remove it from the Project Settings → Extra Tags for GameActivity.
Otherwise, if you haven’t defined any extra tags in your project settings, it would be best to check plugins and their UPL/APL XML files to make sure they aren’t adding this tag manually either.
