When editing a multipage spreadsheet using CALC, pasting a collection of cells, the app crashes, and corrupts the file. The file repair works fine. Multiple attempts produce the same app crash. It's as though there is some maximum number of rows and/or calculations that causes the app to crash.
Please test in safe mode, Menu/Help/Restart in Safe Mode 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.
