Hi,
A NullReferenceException is trigging when trying to load a basic instance of the scheduler, particularly when SfScheduler<TValue>.OnPropertyChangeHandler().MoveNext is called. Code reference and error log below. This has happened with 18.4.0.32, 18.4.0.31, 18.4.0.30, and 18.3.0.53.
**.razor file**
@page "/"
@page "/admin/calendar"
@using Syncfusion.Blazor.Schedule
@using Syncfusion.Blazor.DropDowns
@using Microsoft.AspNetCore.Components.Authorization
@if (!string.IsNullOrEmpty(error))
{
<p>@error</p>
}
<AuthorizeView>
<div id="schedule-container">
<SfSchedule Width="100%" Height="100%" TValue="ShiftReadEditDto" CurrentView="currentView">
