MaterialTimePicker crashing with AppCompatButton cannot be cast to MaterialButton

 <style name="AppTheme" parent="Theme.MaterialComponents.Light.Bridge">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorPrimary</item>
 </style>

When when I attempt to display the new material time picker:

MaterialTimePicker.newInstance().show(supportFragmentManager, "time")

I get this crash:

java.lang.ClassCastException: androidx.appcompat.widget.AppCompatButton cannot be cast to com.google.android.material.button.MaterialButton

Your help would be greatly appreciated 🙏🏽.

There was a bug with 1.3.0-alpha02 with a .Bridge theme.

It was fixed starting with 1.3.0-alpha03.
