Hello, you should notice the same error after update TextView: "android:textAppearance="?attr/textAppearanceHeadline6""

To solve this error update your styles.xml from <style name="AppTheme" parent="Theme.MaterialComponents.DayNight"> to <style name="AppTheme" parent="Theme.MaterialComponents.DayNight">

@CoryBouchard Thank you for reaching out to us.

Since you’re using Android Studio 4.0.x, make this change to your res > values > styles.xml file. Change the parent app theme from Theme.AppCompat.Light.DarkActionBar to Theme.MaterialComponents.DayNight.DarkActionBar.

<style name="Theme.Affirmations" parent="Theme.MaterialComponents.DayNight.DarkActionBar">

It is highly recommended to always use the latest version of the Android Studio. Current latest version is Android Studio 4.1.
@gszesiek Thank you for the response.

Thank you so much for reporting this issue. This is fixed and will be published soon.
