Exception: "String was not recognized as a valid DateTime" for Czech iPhone user

We received a crash report from the SfDatePicker when a user tried to set a date value in our application

DateTimeParse.ParseExact (System.ReadOnlySpan`1[T] s, System.ReadOnlySpan`1[T] format, System.Globalization.DateTimeFormatInfo dtfi, System.Globalization.DateTimeStyles style)
DateTime.ParseExact (System.String s, System.String format, System.IFormatProvider provider)
SfDatePicker+<>c__DisplayClass26_0.<UpdateDays>b__0 ()
NSAsyncActionDispatcher.Apply ()
(wrapper managed-to-native) UIKit.UIApplication.UIApplicationMain(int,string[],intptr,intptr)
UIApplication.Main (System.String[] args, System.String principalClassName, System.String delegateClassName)
Application.Main (System.String[] args)

The user is based in the Czech Republic with their iPhone 8 running iOS 15.6 set to the Slovak language. I expect this is an issue with the code trying to get the current date and parsing an unknown/non-standard datetime format for the user's current culture.

As this is within the SF library I cannot fix this and would appreciate any feedback if there is something that we can do short of waiting for a SF package update.
