Office recovery not working, Office won't open

System crashed, when it rebooted now writer recovery is not working and Libre office won’t open. I’ve rebooted and tried several times, I click start recovery and nothing happens. I can’t find a way to bypass that. None of the other programs in office will open either, the recovery just opens everytime with the same 1 document. Fairly new to this non windows world (which I love now), so be gentle please. What can I do?

Please have a look at Libre Office keeps crashing and the recovery doesn’t work. What do I do? (and the linked answers).
