Lubuntu 18.04.1 with LO 6.0.3.2.
All components of LO open except Writer.
Writer starts the border content of a window, then quits.
I also have Abiword installed as part of the Lubuntu package.
The file in .config/libreoffice is ‘4’.
I have uninstalled Writer, then re-installed, still will not open.
There are no other problems with the general operation of this machine, other than an occasional freeze which was occurring with a previous version of Lubuntu that had Writer working fine.
