Kendo.Mvc.UI.GridBoundColum.SerializeValues throws an exception when using an Enum, decorated with FlagsAttribute.
This is a regression introduced with v2022.2.510. Possibly related to telerik/kendo@423e1e9
Using a ForeignKey column, bound to Enum, where the Enum has the FlagsAttribute throws an exception:
columns.ForeignKey(m => m.MyEnum, ....); // MyEnum is an enum with the FlagsAttribute
Using an Enum, decorated with FlagsAttribute should be possible, as in previous versions and an exception should not be thrown.
