Exception on opening xlsb file

Hi, Aspose team,
We have an issue with the opening of the Excel workbook. It can be opened in MS Excel without any problem but in Aspose.Cells there is an exception.

 System.ArgumentOutOfRangeException
  HResult=0x80131502
  Message=Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: startIndex

Workbook: tmp1BDC.zip (6.9 KB)

Workbook wb = new Workbook(fName);

Aspose.Cells 21.12.0.0
Microsoft Excel for Office 365 MSO (Version 2111 Build 16.0.14701.20254) 64 bit

@licenses,

Please notice, I am able to reproduce the issue as you mentioned by loading your template XLSB file. I found an exception “Index was out of range. Must be non-negative and less than the size of the collection” on opening the XLSB file. I have logged a ticket with an id “CELLSNET-50138” for your issue. We will look into it soon.

Once we have an update on it, we will let you know.
