Left LBO open over night to work on a document in the morning. When i go up I noticed that the electric was out over night. I booted the computer back on, and when i opened LBO, my recent opened documents display board was empty. I had to go to Documents and reopen the ones I had open. Also there was a blue line notice saying welcome to the new version and would I like to see the chnages. Well I had the lastest version 24.2.5. What made LBO open as if I just installed it? And of course there would be no recent documents icons either.
I suppose the user profile was damaged in the crash and a new one was created. See LibreOffice user profile - The Document Foundation Wiki
