Office won't open

FC43
/usr/bin/libreoffice --calc
The starting popup shows, the progression bar run and [… nothing ] just sits there. Was working. Here’s what I’ve done: I installed Nvidia drivers - nvidia-smi wouldn’t run. Google said: Disable Secure Boot. I did. nvidia-smi now runs. libreoffice won’t. -

The Nvida drivers are not a absolute requirement - although would be nice to have. Suggestions please. TIA

Oh, nevermind @$!@$^*!@$# computers
