Mat-datepicker Makes The App Crash Without Logged Error

I've got this page component template at the url /demo Which renders fine, but

Solution 1:

A solution is to additionally import the optional Material module MatNativeDateModule. No dependency is explicitly stated in Material's doc on mat-datepicker, but it seems to be required in some cases.

Thanks to @pengyy 's answer on this question that helped me get to this solution.
