I have used OpenOffice for years with no problem. In the last year or so it crashed almost daily. Resetting the user profile fixed it, but then in a day or two it crashed again. I was told LibreOffice would not have that problem, so I switched to it. But LibreOffice is doing the same thing. Every time this happens I lose all my unsaved work (I usually have several text documents and spreadsheets open), and I must rebuild my user profile anew. My user profile is complicated and takes me almost an hour to re-enter it all in a new user profile.
This problem makes both programs unusable for me, and it seems my only option is to buy Microsoft Office.
I am using LibreOffice 126.96.36.199 on Windows 10 Home version 2004. I have no third party anti-virus. Controlled folder access is off. I am using Safe Mode now, but Safe Mode does not access my user profile. Safe Mode restart in “last known working condition” did not fix the problem.
