Issue with recyclerview dependency after migrating to androidx

Question

I'm completely rebuilding an old project, and have only kept the xml files (which show no error). I chose to update to androidx, and have synced all dependencies correctly, except for recyclerview. Whenever I try to sync, it would show the error log listed below.

android:useAndroidX=true and android:useJetifier=true are both set in gradle.properties file. No errors were detected in any xml file. I triedd Invalidating caches/restarting, rebooting the whole system, and cleaning the project. I actually don't know what else to do.

The error is happening only when I add one or both these dependencies:

 implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha05'
 implementation 'androidx.recyclerview:recyclerview-selection:1.1.0-alpha05'

I tried adding and removing each dependency individually. only those produced the error.

Error
