Error Linq query

Hi all,

we have read range activity and assing with linq query.
In attached the file input
File input.xlsx (8.9 KB)

Below the query used

dtInputProva.AsEnumerable().Where(Function(row) Not dtFinal1.AsEnumerable().
Select(Function(r) r.Field(Of String)(“Concat”)).Any(Function(x) x = row.Field(Of String)(“Concat”))).

when we execute this workflow we have this issue

Could you support us?
