The issue is a regression introduced in R3 2019. When the cells in a hidden column are with IsWrapped=true, an ArgumentOutOfRangeException is thrown during the text measuring. The behavior is related to SpreadProcessing as well.

Workaround: Remove the wrapping from the hidden cells:

var usedCellRange = workbook.ActiveWorksheet.GetUsedCellRange(new IPropertyDefinition[] { CellPropertyDefinitions.IsWrappedProperty});

for (int row = usedCellRange.FromIndex.RowIndex; row <= usedCellRange.ToIndex.RowIndex; row++)
{
    for (int column = usedCellRange.FromIndex.ColumnIndex; column <= usedCellRange.ToIndex.ColumnIndex; column++)
    {
        if (workbook.ActiveWorksheet.Columns[column].GetHidden().Value)
        {
            workbook.ActiveWorksheet.Cells[row, column].SetIsWrapped(false);
        }
    }
}

Hello,

In the spreadsheet control you cannot link/use in a function cells from one work sheet to cell(s) in another work sheet. Would like to have the same behavior and functionality of Excel, which allows you to use data from one sheet in any other sheet in the work book. Need the ability to create a sum of (or any other function available) cells from another worksheet in my current worksheet, within the same workbook.
