Blazor multiselect checkbox broken after package update 20.2.0.40
Hello,
I upgraded to Syncfusion.Blazor.DropDowns (>= 20.2.0.40) and I started receiving
Unhandled exception rendering component: Object reference not set to an instance of an object.
System.NullReferenceException: Object reference not set to an instance of an object.
