Has anyone come across a similar issue, as I have not found any solutions to this problem in any forum.

After migrating to AndroidX, I had a similar issue and the issue was because of Guava. The way I resolved it was to include the following:

configurations {
    all*.exclude group: 'com.google.guava', module: 'listenablefuture'
}

In the (Module:app), most solutions suggest that if you encounter this issue you include the following, in your module gradle:

implementation("android.arch.work:work-runtime:1.0.0-alpha09") {
    exclude group: 'com.google.guava', module: 'listenablefuture' 
}

This results in the following issue: Program type already present androidx.concurrent.futures.DirectExecutor.
