Getting error when clicking on calendar icon in TelerikDatePicker in a Blazor Web Server app:
Error: System.NullReferenceException: Object reference not set to an instance of an object.
at Telerik.Blazor.Components.TelerikDatePicker`1.get_AriaActiveDescendant()
at Telerik.Blazor.Components.TelerikDatePicker`1.<BuildRenderTree>b__154_1(RenderTreeBuilder __builder2)
at Microsoft.AspNetCore.Components.CascadingValue`1.Render(RenderTreeBuilder builder)
at Microsoft.AspNetCore.Components.Rendering.ComponentState.RenderIntoBatch(RenderBatchBuilder batchBuilder, RenderFragment renderFragment, Exception& renderFragmentException)
Doesn't happen to all DatePickers, only on certain ones.
Also, this only happens when the app is published to IIS on Windows Server 2019. This does not happen when running in development in Visual Studio 2022 Professional.
Using Telerik UI for Blazor v3.5
I use TelerikDateTimePicker inside a form. When I try to clean up TelerikDateTimePicker using keyboard backspace and then click mouse by Calendar icon I get error: System.NullReferenceException: Object reference not set to an instance of an object.
