class does not implement ActivityResultLauncher AS ArcticFox

问题

I just installed the last version of Android Studio Arctic Fox | 2020.3.1 Canary 3.

When I open my projects, studio shows error for all of the fragments :

Class 'MapsFragment' is not abstract and does not implement abstract base class member public abstract fun <I : Any!, O : Any!> prepareCall(contract: ActivityResultContract<I!, O!>, callback: ActivityResultCallback<O!>): ActivityResultLauncher<I!> defined in androidx.fragment.app.Fragment

is it AS bug?
