I use a freeware called Interactive Calendar. It has a transparent calendar on the screen, and allows editing "calendar events." I use it pretty much as a daily diary, if you will, but also for posting appointments. When I attempt to load a calc spreadsheet after working with the calendar, the spreadsheet loads without the icon bar, and generally crashes if you try to close it. When you reload, it reloads okay, and is completely functional. After calc has been used, however, the calendar program has a crash, but loads immediately, and when calc is used again, it will crash on loading. I suspect they are trying to write to the same dll in windows, since these are both windows programs. Frustrating, but thought I would bring it to someone's attention since it may also happen with other programs if they are writing to a shared dll, or whatever. I was always a fan of programs that kept all their parts in their own directory, and this was why - shared files that can be written to in Windows tend to be used by more than one program. It is possible that the calendar is keeping a file open since it is up all the time, and office is only loaded as needed.
Just to clarify: Which LibreOffice version are you using? Which Windows version are you using? LibreOffice 5.2 has a crash reporter, that might be able to catch the crash and then you could submit the crash data to a server with the click of a button. It might not catch every sort of crash, though. Set to NEEDINFO. Change back to UNCONFIRMED after you have provided the information.
