When using the following android lifecycle dependencies:
// ViewModel
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"
// ViewModel utilities for Compose
implementation "androidx.lifecycle:lifecycle-viewmodel-compose:$lifecycle_version"
higher than version 2.5.1 I'm getting the errors below. To fix the error I just went back to versions below 2.5.1 (inclusive). I do not know what might be causing the error. Maybe a breaking change in the dependency? It is strange because the only dependency I added to my project were the ones above.
Here is my build.gradle

I had to trim the error message above.
This was not my first time using the android.lifecycle dependencies. I expected things to work normal but got Duplicate class error on with android.lifecycle version 2.6.1. Solved by going down version. However want to know the reason for the error.
