Calc fails on trying to open large workbook

Hi, All. This is getting very annoying. Until 2 weeks ago, I had no problem opening my CostOfMoney spreadsheet/workbook. It is book with 17 sheets and is about 16Mb in size. Two weeks ago I added the 17th sheet, and now when opening, it instead just closes LibreOffice without any error messages. THis is similar to a problem I’ve had with this workbook forever: I add new lines to the sheets, then enter one piece of data to the line, and copy/paste the formulae from the previous line, and LO closes with no error message. I was being forced to do the copy/paste using OpenOffice.

Any ideas? Too many sheets? Too large a file?

Please attach a sample file, reduce the size as much as possible without private information,
and paste the information in Menu/Help/About LibreOffice, there is a copy icon.
