Following on from my previous question where LO crashed then would not launch even after uninstalling then installing the latest version, after I tried a few more times it did finally launch. LO then tried unsuccessfully several times to recover 2 documents and finally loaded up.
So I don’t know how the problem fixed itself although there was a major Win10 update in the intervening period between when LO would not launch and when it did, so maybe that was the cure. Anyway, I did not receive any response to my initial question so this is just to inform whoever is supposed to be concerned with these questions - somewhat undefined.
