Angular Material 10.2.5, same issue, I have 2 lazy loaded modules: Core and Backoffice. The ShowOnDirtyErrorStateMatcher works fine in the Backoffice but not in Core which is very weird.

@rodoch, what suggested patch?

``` const now = new Date(); return eachDayOfInterval({ start: startOfISOWeek(now), end: endOfISOWeek(now), }).map((day) => format(day, formatString, { locale })); ``` formatString is a variant of 'i' (i, ii, iii, iiii...)
