Exception using DataGrid 18.2.0.58

[T]

Net 5 RC1, Blazor Server app.

DataGrid 18.2.0.57 works as expected.

Updating to 18.2.0.58 results in a runtime exception.

After downgrading back to 18.2.0.57 DataGrid works as expected.

I am also getting this issue since upgrading to 18.2.58......

It looks to be associated to Aggregates on a Stacked Column. If you comment out the Aggregate then the error goes away. Not helpful I know - but it will get you up and running again. 

Syncfusion.......Please be aware.
