Failed to load Libmain.so The application will terminate

I am creating Il2cpp build app bundle (~aab file) after publishing it on play store getting “Failed to load Libmain.so The application will terminate” Error.

I rechecked aab file by WinRAR too still in its lib folder it doesn’t have libmain.so file however ARMV7 Have libmain.so file but in ARM64 doesn’t have libmain.so file

I dont know why libmain.so file is not generating in aab file.

Unity version :- 2019.3.0f6

You can go to your mainTemplate.gradle then comment or remove the exclude statements as shown below. for me Idk how these statements came to be.

// Android Resolver Exclusions Start
android {
  packagingOptions {
     // exclude ('/lib/arm64-v8a/*' + '*')
     // exclude ('/lib/armeabi/*' + '*')
    //  exclude ('/lib/mips/*' + '*')
    //  exclude ('/lib/mips64/*' + '*')
     // exclude ('/lib/x86/*' + '*')
     // exclude ('/lib/x86_64/*' + '*')
  }
}

You can also run Android dependency resolver again.
