React native – java.lang.UnsatisfiedLinkError: dlopen failed: library "libreact_featureflagsjni.so" not found

I was manually upgrading a react-native app from 0.67.2 to 0.76.2 (making changes in the required files). I was able to build the android app successfully after a day of debugging here and there. But when I tried to install it and run it, it throws the following runtime error. I’ve looked into the intermediates folder, but this file is not available. Then I’ve disabled the new architecture and hermes engin and tried to run. But that throws java.lang.UnsatisfiedLinkError: dlopen failed: library "libjscexecutor.so not found"

Thanks in advance for your help
