When you click on the CardView, a DialogFragment should appear, but the application crashes, writes the following in the logs

I have a similar Adapter, but when called, everything works, that is, the problem is not in the DialogFragment, since everything works when called from another fragment.
Fragment that the CardView is in

An Adapter that has the same functionality, but why does it work, explain the difference?
