design: 'material' causes app to crash

The report gives a reproducible call to DateTimePickerAndroid.open with design: 'material' and a crash trace naming MaterialDatePicker; it does not identify repository files or tests. Start by reading the Android implementation of the material design option and checking how the Expo config plugin sets the app theme. Done means the date picker opens in the reported Expo development build without the missing materialCalendarTheme crash.

Bug report

Summary

Setting the design property to material causes the app to crash upon opening the date picker.
Using Expo v53, datetimepicker v8.4.1
Included the @react-native-community/datetimepicker plugin both with no config and with some basic theming which works for the default picker. Running on an Expo development build.

Crash details:

java.lang.IllegalArgumentException: com.google.android.material.datepicker.MaterialDatePicker requires a value for the {bundle-identifier}:attr/materialCalendarTheme attribute to be set in your app theme. You can either set the attribute in your theme or update your theme to inherit from Theme.MaterialComponents (or a descendant).
