Kotlin android data binding issue fails in app:kaptDebugKotlin

Question

after enabling both data binding and view binding

`
buildFeatures {
        viewBinding true
        dataBinding true
      
    }`

and started giving this error while running app but not while syncing gradle. Tried clean/rebuild and invalidate cache & restart, nothing is helping.Everything added correctly in gradle.

    > Task :app:kaptDebugKotlin

This is the problematic class that the compiler is complaining about while running app

Answering it because want to show the emphasis of when something peculiar is wrong with your data binding or view binding it's almost certain that there is some issue in layout files.

As with my case the confusing part was the generated binding class was not part of my project idk why it was generating but after searching all my layout files I discovered one import from support library not androidx thus creating this weird issue.
