NullReferenceException converting file to XLS

Scenario: Converting XLSM to XLS. Aspose.Cells 22.1.

Issue: NullReferenceException is thrown by the Save method. The issue is present from Aspose.Cells 21.12 (cannot be reproduced with Aspose.Cells 21.11).

var filePath = @"sample.xlsm";
var wb = new Workbook(filePath, new LoadOptions());
wb.Save(filePath + ".xls", SaveFormat.Excel97To2003);

Thanks.
