[Datetimepicker] Cannot read properties of undefined (reading 'type')

[Res42]

The datetimepicker throws an error after updating to 19.0.1, but only when I programmatically set its value with writeValue. This did not throw when I was on version 18.4.0.

ERROR TypeError: Cannot read properties of undefined (reading 'type')

I made a minimal repro here: https://stackblitz.com/edit/stackblitz-starters-5yuruzkt?file=src%2Fmain.ts (check the console for the error).
