Adding dependency to androidx.fragment:fragment-ktx:1.3.0-beta01 causes runtime exception

I need to add a dependency to androidx.fragment:fragment-ktx:1.3.0-beta01 in an app that uses Android navigation and dynamic features. I need the dependency to call setFragmentResult, but the app would stop working with an exception of

"no class definition found"

At runtime. Please help...

UPDATE

This is my app build gradle

UPDATE 2

If I move the dependency from the Dynamic Feature that actually uses it to the main app (app gradle), the app doesn't start and I get the following exception:

Unable to start activity

ComponentInfo{it.kfi.lorikeetmobile/it.kfi.lorikeetmobile.ui.MainActivity}: android.view.InflateException: Binary XML file line #12: Binary XML file line #11: Error inflating class fragment

.... I do not understand what to do more
